Practice questions on Kinematics - Equations of Motion — with answers

Try each question first, then open the answer. Explanations are included.

1. An object starts with an initial velocity of 5 m/s and accelerates uniformly at 5 m/s^2 for 7 seconds. What distance does it cover? (s = ut + 1/2at^2)

A155.5
B162.5
C130.081
D157.5

Show answer

Answer: D

s = ut + (1/2)at^2 = (5 x 7) + (0.5 x 5 x 7^2) = 35 + 122.5 = 157.5 m.

2. An object starts with an initial velocity of 8 m/s and accelerates uniformly at 6 m/s^2 for 1 seconds. What is its final velocity? (v = u + at)

Show answer

Answer: C

v = u + at = 8 + (6 x 1) = 8 + 6 = 14 m/s.

3. An object starts with an initial velocity of 4 m/s and accelerates uniformly at 3 m/s^2 over a distance of 4 m. What is its final velocity? (v^2 = u^2 + 2as)

A6.325
B7.325
C8.325
D16.325

Show answer

Answer: A

v^2 = u^2 + 2as = 4^2 + (2 x 3 x 4) = 16 + 24 = 40. So v = sqrt(40) = 6.325 m/s.

4. An object starts with an initial velocity of 10 m/s and accelerates uniformly at 9 m/s^2 over a distance of 8 m. What is its final velocity? (v^2 = u^2 + 2as)

A15.62
B15.589
C16.418
D17.62

Show answer

Answer: A

v^2 = u^2 + 2as = 10^2 + (2 x 9 x 8) = 100 + 144 = 244. So v = sqrt(244) = 15.62 m/s.

5. An object starts with an initial velocity of 4 m/s and accelerates uniformly at 1 m/s^2 for 6 seconds. What is its final velocity? (v = u + at)

A20
B10.302
C9
D10

Show answer

Answer: D

v = u + at = 4 + (1 x 6) = 4 + 6 = 10 m/s.
