1.Easy
t (s)v (m/s)9 s10.5

A car moving at 6 m/s speeds up with a constant acceleration of 0.5 m/s² for 9 s. How far does it travel in that time? Find s.

v₀ = 6 m/sa = 0.5 m/s²t = 9 s
s = m
2.Easy
t (s)v (m/s)7 s26.5

A car moving at 2 m/s speeds up with a constant acceleration of 3.5 m/s² for 7 s. How far does it travel in that time? Find s.

v₀ = 2 m/sa = 3.5 m/s²t = 7 s
s = m
3.Medium
t (s)v (m/s)2.083 s12.5

A car driving at 45 km/h brakes with a constant deceleration of 6 m/s² until it stops. Find the braking distance s.

v₀ = 45 km/ha = −6 m/s²v = 0
s = m
4.Medium
t (s)v (m/s)t = ?27.78

A car driving at 100 km/h brakes with a constant deceleration of 8 m/s² until it stops. How long does braking take? Find t.

v₀ = 100 km/ha = −8 m/s²v = 0
t = s
5.Hard
v₀ = 18 m/s30 m

A ball is thrown straight up at 18 m/s from the edge of a roof 30 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 = 30 mg = 9.81 m/s²
t = s
6.Hard
AB: 24 m/s35 m

Ball A is dropped from rest from a height of 35 m. At the same instant ball B is thrown straight up from the ground directly below at 24 m/s. Ignore air resistance and use g = 9.81 m/s². At what height y above the ground do they meet?

H = 35 mv0B = 24 m/sg = 9.81 m/s²
y = m

Answer key

  1. 1. s = 74.25 m
  2. 2. s = 99.75 m
  3. 3. s = 13.02 m
  4. 4. t = 3.472 s
  5. 5. t = 4.914 s
  6. 6. y = 24.57 m
