1.Easy
t (s)v (m/s)6 sv = ?

A car moving at 16 m/s speeds up with a constant acceleration of 4 m/s² for 6 s. Find its final speed v.

v₀ = 16 m/sa = 4 m/s²t = 6 s
v = m/s
2.Easy
t (s)v (m/s)4 sv = ?

A car moving at 10 m/s speeds up with a constant acceleration of 3.5 m/s² for 4 s. Find its final speed v.

v₀ = 10 m/sa = 3.5 m/s²t = 4 s
v = m/s
3.Medium
t (s)v (m/s)t = ?33.33

A car driving at 120 km/h brakes with a constant deceleration of 6.5 m/s² until it stops. How long does braking take? Find t.

v₀ = 120 km/ha = −6.5 m/s²v = 0
t = s
4.Medium
t (s)v (m/s)t = ?20

A car driving at 72 km/h brakes with a constant deceleration of 4.5 m/s² until it stops. How long does braking take? Find t.

v₀ = 72 km/ha = −4.5 m/s²v = 0
t = s
5.Hard
AB: 27 m/s50 m

Ball A is dropped from rest from a height of 50 m. At the same instant ball B is thrown straight up from the ground directly below at 27 m/s. Ignore air resistance and use g = 9.81 m/s². At what height y above the ground do they meet?

H = 50 mv0B = 27 m/sg = 9.81 m/s²
y = m
6.Hard
v₀ = 19 m/s40 m

A ball is thrown straight up at 19 m/s from the edge of a roof 40 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 = 19 m/sh₀ = 40 mg = 9.81 m/s²
t = s

Answer key

  1. 1. v = 40 m/s
  2. 2. v = 24 m/s
  3. 3. t = 5.128 s
  4. 4. t = 4.444 s
  5. 5. y = 33.18 m
  6. 6. t = 5.387 s
