1.Easy
t (s)v (m/s)7 sv = ?

A car moving at 14 m/s speeds up with a constant acceleration of 1 m/s² for 7 s. Find its final speed v.

v₀ = 14 m/sa = 1 m/s²t = 7 s
v = m/s
2.Easy
t (s)v (m/s)8 sv = ?

A car moving at 8 m/s speeds up with a constant acceleration of 1 m/s² for 8 s. Find its final speed v.

v₀ = 8 m/sa = 1 m/s²t = 8 s
v = m/s
3.Medium
t (s)v (m/s)t = ?20

A car driving at 72 km/h brakes with a constant deceleration of 5 m/s² until it stops. How long does braking take? Find t.

v₀ = 72 km/ha = −5 m/s²v = 0
t = s
4.Medium
policea = 6 m/s²car31 m/s

A car speeding at a constant 31 m/s passes a police car standing still. At that moment the police car starts and accelerates uniformly at 6 m/s². How far from its starting point does the police car catch up? Find d.

vcar = 31 m/sapolice = 6 m/s²v0,police = 0
d = m
5.Hard
v₀ = 8 m/s25 m

A ball is thrown straight up at 8 m/s from the edge of a roof 25 m above the ground. Ignore air resistance and use g = 9.81 m/s². Find the greatest height hmax above the ground.

v₀ = 8 m/sh₀ = 25 mg = 9.81 m/s²
hmax = m
6.Hard
v₀ = 9 m/s30 m

A ball is thrown straight up at 9 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 = 9 m/sh₀ = 30 mg = 9.81 m/s²
t = s

Answer key

  1. 1. v = 21 m/s
  2. 2. v = 16 m/s
  3. 3. t = 4 s
  4. 4. d = 320.3 m
  5. 5. hmax = 28.26 m
  6. 6. t = 3.555 s
