Q. A player hits a ball at an angle of 30 degrees with the horizontal. If the initial speed is 20 m/s, what is the vertical component of the velocity? (2022)
A.
10 m/s
B.
15 m/s
C.
20 m/s
D.
5 m/s
Solution
Vertical component = Initial speed × sin(angle) = 20 m/s × sin(30°) = 20 m/s × 0.5 = 10 m/s.
Q. A projectile is launched at an angle of 30° with the horizontal with an initial velocity of 40 m/s. What is the horizontal range of the projectile? (Take g = 10 m/s²)
A.
160 m
B.
200 m
C.
80 m
D.
120 m
Solution
Range R = (u² * sin(2θ))/g = (40² * sin(60°))/10 = (1600 * √3/2)/10 = 80√3 m ≈ 138.56 m.
Q. A projectile is launched with an initial velocity of 30 m/s at an angle of 30 degrees to the horizontal. What is the horizontal range of the projectile? (Take g = 10 m/s²)
A.
90 m
B.
75 m
C.
100 m
D.
120 m
Solution
Range R = (u² * sin(2θ))/g = (30² * sin(60°))/10 = (900 * √3/2)/10 = 45√3 m ≈ 90 m.

Q. A radar system can detect objects up to a distance of 100 km. If it scans at a speed of 20 km/h, how long will it take to complete a full scan? (2023)
A.
4 hours
B.
5 hours
C.
6 hours
D.
7 hours
Solution
Time = Distance / Speed = 100 km / 20 km/h = 5 hours
