1.Easy
t (s)v (m/s)5 sv = ?

A car moving at 10 m/s speeds up with a constant acceleration of 2 m/s² for 5 s. Find its final speed v.

v₀ = 10 m/sa = 2 m/s²t = 5 s
v = m/s
2.Easy
t (s)v (m/s)4 s16

A car moving at 0 m/s speeds up with a constant acceleration of 4 m/s² for 4 s. How far does it travel in that time? Find s.

v₀ = 0 m/sa = 4 m/s²t = 4 s
s = m
3.Medium
t (s)v (m/s)2.778 s13.89

A car driving at 50 km/h brakes with a constant deceleration of 5 m/s² until it stops. Find the braking distance s.

v₀ = 50 km/ha = −5 m/s²v = 0
s = m
4.Medium
t (s)v (m/s)2.727 s15

A car driving at 54 km/h brakes with a constant deceleration of 5.5 m/s² until it stops. Find the braking distance s.

v₀ = 54 km/ha = −5.5 m/s²v = 0
s = m
5.Hard
v₀ = 6 m/s35 m

A ball is thrown straight up at 6 m/s from the edge of a roof 35 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 = 6 m/sh₀ = 35 mg = 9.81 m/s²
t = s
6.Hard
v₀ = 14 m/s5 m

A ball is thrown straight up at 14 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 = 14 m/sh₀ = 5 mg = 9.81 m/s²
t = s

Answer key

  1. 1. v = 20 m/s
  2. 2. s = 32 m
  3. 3. s = 19.29 m
  4. 4. s = 20.45 m
  5. 5. t = 3.352 s
  6. 6. t = 3.175 s
