Q. A block of mass 5 kg is resting on a horizontal surface. If the coefficient of kinetic friction between the block and the surface is 0.3, what is the frictional force acting on the block when it is sliding?
A.
5 N
B.
10 N
C.
15 N
D.
20 N
Solution
Frictional force (Ff) = μk * N = μk * mg = 0.3 * (5 kg * 10 m/s²) = 15 N.
Q. A block of mass 5 kg is resting on a horizontal surface. If the coefficient of static friction is 0.4, what is the maximum static frictional force acting on the block?
A.
10 N
B.
20 N
C.
15 N
D.
25 N
Solution
Maximum static frictional force (Fs) = μs * N = μs * mg = 0.4 * (5 kg * 10 m/s²) = 20 N.
Q. A block on a frictionless surface is attached to a spring and undergoes simple harmonic motion. If the spring constant is 200 N/m and the mass is 2 kg, what is the period of oscillation?
A.
0.5 s
B.
1 s
C.
2 s
D.
4 s
Solution
The period T is given by T = 2π√(m/k). Here, T = 2π√(2/200) = 2π√(0.01) = 2π(0.1) = 0.2π ≈ 0.63 s.
Q. A block slides down a frictionless incline of angle 30 degrees. If the incline has a coefficient of kinetic friction of 0.2, what is the acceleration of the block?
A.
4.9 m/s²
B.
3.9 m/s²
C.
2.9 m/s²
D.
1.9 m/s²
Solution
Net force = mg sin(30) - μmg cos(30). Acceleration a = (mg sin(30) - μmg cos(30))/m = g(sin(30) - μ cos(30)). Substituting g = 10 m/s² gives a = 10(0.5 - 0.2 * √3/2) = 4.9 m/s².
Q. A boat can travel 30 km upstream in 2 hours. What is the speed of the current if the speed of the boat in still water is 15 km/h?
A.
2.5 km/h
B.
3 km/h
C.
3.5 km/h
D.
4 km/h
Solution
Speed upstream = Speed of boat - Speed of current. Speed upstream = 30 km / 2 h = 15 km/h. Therefore, 15 km/h - Speed of current = 15 km/h, so Speed of current = 0 km/h.
Q. A boat can travel at 10 km/h in still water. If it is moving downstream in a river flowing at 5 km/h, what is the speed of the boat relative to the riverbank?
A.
5 km/h
B.
10 km/h
C.
15 km/h
D.
20 km/h
Solution
Speed downstream = Speed of boat + Speed of river = 10 km/h + 5 km/h = 15 km/h.
