1.Easy
t (s)v (m/s)6 s24

A car moving at 12 m/s speeds up with a constant acceleration of 2 m/s² for 6 s. How far does it travel in that time? Find s.

v₀ = 12 m/sa = 2 m/s²t = 6 s
s = m
2.Easy
t (s)v (m/s)7 s16.5

A car moving at 6 m/s speeds up with a constant acceleration of 1.5 m/s² for 7 s. How far does it travel in that time? Find s.

v₀ = 6 m/sa = 1.5 m/s²t = 7 s
s = m
3.Medium
t (s)v (m/s)2.083 s16.67

A car driving at 60 km/h brakes with a constant deceleration of 8 m/s² until it stops. Find the braking distance s.

v₀ = 60 km/ha = −8 m/s²v = 0
s = m
4.Medium
t (s)v (m/s)1 s33.33

A driver moving at 120 km/h sees an obstacle. Her reaction time is 1 s, after which the car brakes with a constant deceleration of 5 m/s². Find the total stopping distance d from the moment she sees the obstacle.

v₀ = 120 km/htr = 1 sa = −5 m/s²
d = m
5.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. Find the greatest height hmax above the ground.

v₀ = 18 m/sh₀ = 15 mg = 9.81 m/s²
hmax = m
6.Hard
AB: 25 m/s15 m

Ball A is dropped from rest from a height of 15 m. At the same instant ball B is thrown straight up from the ground directly below at 25 m/s. Ignore air resistance and use g = 9.81 m/s². When do the balls meet? Find t.

H = 15 mv0B = 25 m/sg = 9.81 m/s²
t = s

Answer key

  1. 1. s = 108 m
  2. 2. s = 78.75 m
  3. 3. s = 17.36 m
  4. 4. d = 144.4 m
  5. 5. hmax = 31.51 m
  6. 6. t = 0.6 s
