Q. A man is standing 40 meters away from a building. If the angle of elevation to the top of the building is 30 degrees, what is the height of the building?
Q. A man is standing 50 meters away from a vertical pole. If he looks up at an angle of elevation of 60 degrees to the top of the pole, what is the height of the pole?
A.
25 m
B.
30 m
C.
35 m
D.
40 m
Solution
Using tan(60°) = height/50, we have √3 = height/50. Therefore, height = 50√3 ≈ 86.6 m.
Q. A man is standing on a hill 80 meters high. If he looks at a point on the ground at an angle of depression of 45 degrees, how far is the point from the base of the hill?

A.
36.87 degrees
B.
45 degrees
C.
60 degrees
D.
30 degrees
Solution
Using tan(θ) = height/distance, we have tan(θ) = 15/20. Therefore, θ = tan⁻¹(0.75) which is approximately 36.87 degrees.

A.
20 m
B.
40 m
C.
20√3 m
D.
40√3 m
Solution
Using tan(60°) = height/distance, we have distance = height/tan(60°) = 40/√3 = 20√3 m.
Q. A man is standing on the ground and looking at the top of a building. If the angle of elevation is 45 degrees and he is 10 meters away from the building, what is the height of the building?
Q. A man is standing on the ground and looking at the top of a tree. If the angle of elevation is 60 degrees and he is 10 meters away from the base of the tree, what is the height of the tree?
A.
5√3 m
B.
10√3 m
C.
15√3 m
D.
20√3 m
Solution
Using tan(60°) = height/10, we have √3 = height/10. Therefore, height = 10√3 m.
Q. A man is standing on the ground and observes the top of a building at an angle of elevation of 60 degrees. If he is 50 m away from the building, what is the height of the building?
A.
25 m
B.
43.3 m
C.
50 m
D.
86.6 m
Solution
Using tan(60°) = height/50, we have √3 = height/50. Therefore, height = 50√3 ≈ 86.6 m.
Q. A man is standing on the ground and observes the top of a tree at an angle of elevation of 45 degrees. If he is 10 meters away from the tree, what is the height of the tree?
A.
5 m
B.
10 m
C.
15 m
D.
20 m
Solution
Using tan(45°) = height/10, we have 1 = height/10. Therefore, height = 10 m.
Q. A mass attached to a spring oscillates with a damping coefficient of 0.3 kg/s. If the mass is 1 kg and the spring constant is 4 N/m, what is the damping ratio?
A.
0.1
B.
0.3
C.
0.5
D.
0.75
Solution
Damping ratio (ζ) = c / (2√(mk)) = 0.3 / (2√(1*4)) = 0.3 / 4 = 0.075.
Q. A mass is measured as 15.0 kg with an uncertainty of ±0.3 kg. If this mass is used to calculate the force (F = ma) with an acceleration of 9.8 m/s², what is the uncertainty in the force?
A.
0.3 N
B.
2.94 N
C.
0.5 N

Uncertainty in force = a * (uncertainty in mass) = 9.8 * 0.3 = 2.94 N.
Q. A mass is measured as 5.0 kg with an uncertainty of ±0.1 kg. If this mass is used to calculate weight (W = mg), what is the uncertainty in weight if g = 9.8 m/s²?
A.
±0.2 N
B.
±0.5 N
C.
±0.1 N

Uncertainty in weight = g * (uncertainty in mass) = 9.8 * 0.1 = ±0.98 N, rounded to ±1 N.
Q. A mass m is attached to a spring of spring constant k. If the mass is displaced by a distance x from its equilibrium position, what is the restoring force acting on the mass?
A.
kx
B.
-kx
C.
mg
D.
-mg
Solution
The restoring force in simple harmonic motion is given by Hooke's law, which states that the force is proportional to the displacement and acts in the opposite direction. Therefore, the restoring force is -kx.
Q. A mass m is attached to a spring of spring constant k. If the mass is displaced from its equilibrium position and released, what is the time period of the oscillation?
A.
2π√(m/k)
B.
2π√(k/m)
C.
π√(m/k)
D.
π√(k/m)
Solution
The time period T of a mass-spring system in simple harmonic motion is given by T = 2π√(m/k).
Q. A mass m is attached to a string and is whirled in a horizontal circle. If the radius of the circle is halved, what happens to the tension in the string if the speed remains constant?
A.
It doubles
B.
It remains the same
C.
It halves
D.
It quadruples
Solution
Tension T = mv²/r. If r is halved, T doubles for constant speed.
Q. A mass m is attached to a string and is whirled in a vertical circle. At the highest point of the circle, the tension in the string is T. What is the expression for T?
A.
T = mg
B.
T = mg - mv²/r
C.
T = mg + mv²/r
D.
T = mv²/r
Solution
At the highest point, T + mg = mv²/r, thus T = mg - mv²/r.
Q. A mass m is attached to a string and is whirled in a vertical circle. At the highest point of the circle, what is the minimum speed required to keep the mass in circular motion?
A.
√(g*r)
B.
g*r
C.
2g*r
D.
g/2
Solution
At the highest point, the centripetal force is provided by the weight. Minimum speed = √(g*r).
Q. A mass m is attached to a string and is whirled in a vertical circle. At the highest point of the circle, what is the condition for the mass to just complete the circular motion?
A.
Tension = 0
B.
Tension = mg
C.
Tension = 2mg
D.
Tension = mg/2
Solution
At the highest point, the centripetal force is provided by the weight of the mass, so T + mg = mv²/r. For T = 0, mg = mv²/r.
