1.Easy
t (s)v (m/s)9 sv = ?

A car moving at 16 m/s speeds up with a constant acceleration of 3.5 m/s² for 9 s. Find its final speed v.

v₀ = 16 m/sa = 3.5 m/s²t = 9 s
v = m/s
2.Easy
t (s)v (m/s)11 sv = ?

A car moving at 2 m/s speeds up with a constant acceleration of 3 m/s² for 11 s. Find its final speed v.

v₀ = 2 m/sa = 3 m/s²t = 11 s
v = m/s
3.Medium
t (s)v (m/s)0.9 s12.5

A driver moving at 45 km/h sees an obstacle. Her reaction time is 0.9 s, after which the car brakes with a constant deceleration of 6 m/s². Find the total stopping distance d from the moment she sees the obstacle.

v₀ = 45 km/htr = 0.9 sa = −6 m/s²
d = m
4.Medium
t (s)v (m/s)2.5 s12.5

A car driving at 45 km/h brakes with a constant deceleration of 5 m/s² until it stops. Find the braking distance s.

v₀ = 45 km/ha = −5 m/s²v = 0
s = m
5.Hard
v₀ = 13 m/s15 m

A ball is thrown straight up at 13 m/s from the edge of a roof 15 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 = 13 m/sh₀ = 15 mg = 9.81 m/s²
t = s
6.Hard
v₀ = 15 m/s35 m

A ball is thrown straight up at 15 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 = 15 m/sh₀ = 35 mg = 9.81 m/s²
t = s

Answer key

  1. 1. v = 47.5 m/s
  2. 2. v = 35 m/s
  3. 3. d = 24.27 m
  4. 4. s = 15.63 m
  5. 5. t = 3.519 s
  6. 6. t = 4.607 s
