Kinematics worksheet with answers
A car moving at 14 m/s speeds up with a constant acceleration of 1 m/s² for 6 s. Find its final speed v.
A car driving at 36 km/h brakes with a constant deceleration of 7.5 m/s² until it stops. Find the braking distance s.
A car driving at 60 km/h brakes with a constant deceleration of 6 m/s² until it stops. Find the braking distance s.
A stone is dropped from rest into a well. The splash is heard 1.5 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.
A ball is thrown straight up at 12 m/s from the edge of a roof 15 m above the ground. Ignore air resistance and use g = 9.81 m/s². How long after the throw does it hit the ground? Find t.
Answer key
- 1. v = 15 m/s
- 2. v = 20 m/s
- 3. s = 6.667 m
- 4. s = 23.15 m
- 5. d = 10.59 m
- 6. t = 3.357 s
