A car moving at 0 m/s speeds up with a constant acceleration of 2 m/s² for 11 s. Find its final speed v.
Kinematics worksheet with answers
A car moving at 12 m/s speeds up with a constant acceleration of 3 m/s² for 7 s. Find its final speed v.
A car speeding at a constant 31 m/s passes a police car standing still. At that moment the police car starts and accelerates uniformly at 5 m/s². How far from its starting point does the police car catch up? Find d.
A car driving at 108 km/h brakes with a constant deceleration of 4.5 m/s² until it stops. Find the braking distance s.
A ball is thrown straight up at 18 m/s from the edge of a roof 20 m above the ground. Ignore air resistance and use g = 9.81 m/s². Find the greatest height hmax above the ground.
A stone is dropped from rest into a well. The splash is heard 2.4 s after the stone is released. The speed of sound is 343 m/s; ignore air resistance and use g = 9.81 m/s². Find the depth d of the well.
Answer key
- 1. v = 22 m/s
- 2. v = 33 m/s
- 3. d = 384.4 m
- 4. s = 100 m
- 5. hmax = 36.51 m
- 6. d = 26.47 m
