1.Easy
t (s)v (m/s)7 s21

A car moving at 14 m/s speeds up with a constant acceleration of 1 m/s² for 7 s. How far does it travel in that time? Find s.

v₀ = 14 m/sa = 1 m/s²t = 7 s
s = m
2.Easy
t (s)v (m/s)12 s6

A car moving at 0 m/s speeds up with a constant acceleration of 0.5 m/s² for 12 s. How far does it travel in that time? Find s.

v₀ = 0 m/sa = 0.5 m/s²t = 12 s
s = m
3.Medium
t (s)v (m/s)5.051 s27.78

A car driving at 100 km/h brakes with a constant deceleration of 5.5 m/s² until it stops. Find the braking distance s.

v₀ = 100 km/ha = −5.5 m/s²v = 0
s = m
4.Medium
t (s)v (m/s)t = ?25

A car driving at 90 km/h brakes with a constant deceleration of 3.5 m/s² until it stops. How long does braking take? Find t.

v₀ = 90 km/ha = −3.5 m/s²v = 0
t = s
5.Hard
v₀ = 14 m/s20 m

A ball is thrown straight up at 14 m/s from the edge of a roof 20 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 = 14 m/sh₀ = 20 mg = 9.81 m/s²
t = s
6.Hard
v₀ = 18 m/s15 m

A ball is thrown straight up at 18 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.

v₀ = 18 m/sh₀ = 15 mg = 9.81 m/s²
t = s

Answer key

  1. 1. s = 122.5 m
  2. 2. s = 36 m
  3. 3. s = 70.15 m
  4. 4. t = 7.143 s
  5. 5. t = 3.9 s
  6. 6. t = 4.37 s
