1.Easy
t (s)v (m/s)3 s9.5

A car moving at 8 m/s speeds up with a constant acceleration of 0.5 m/s² for 3 s. How far does it travel in that time? Find s.

v₀ = 8 m/sa = 0.5 m/s²t = 3 s
s = m
2.Easy
t (s)v (m/s)6 s9

A car moving at 0 m/s speeds up with a constant acceleration of 1.5 m/s² for 6 s. How far does it travel in that time? Find s.

v₀ = 0 m/sa = 1.5 m/s²t = 6 s
s = m
3.Medium
t (s)v (m/s)4.444 s20

A car driving at 72 km/h brakes with a constant deceleration of 4.5 m/s² until it stops. Find the braking distance s.

v₀ = 72 km/ha = −4.5 m/s²v = 0
s = m
4.Medium
a = 2 m/s²s = 1800 m

A plane starts from rest and accelerates uniformly at 2 m/s² along a runway. Find its speed v after 1800 m.

v₀ = 0a = 2 m/s²s = 1800 m
v = m/s
5.Hard
v₀ = 16 m/s5 m

A ball is thrown straight up at 16 m/s from the edge of a roof 5 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.

v₀ = 16 m/sh₀ = 5 mg = 9.81 m/s²
t = s
6.Hard
v₀ = 10 m/s10 m

A ball is thrown straight up at 10 m/s from the edge of a roof 10 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.

v₀ = 10 m/sh₀ = 10 mg = 9.81 m/s²
t = s

Answer key

  1. 1. s = 26.25 m
  2. 2. s = 27 m
  3. 3. s = 44.44 m
  4. 4. v = 84.85 m/s
  5. 5. t = 3.549 s
  6. 6. t = 2.774 s
