1.Easy
t (s)v (m/s)5 s33.5

A car moving at 16 m/s speeds up with a constant acceleration of 3.5 m/s² for 5 s. How far does it travel in that time? Find s.

v₀ = 16 m/sa = 3.5 m/s²t = 5 s
s = m
2.Easy
t (s)v (m/s)18 s10

A train slows down uniformly from 15 m/s to 10 m/s in 18 s. How far does it travel in that time? Find s.

v₀ = 15 m/sv = 10 m/st = 18 s
s = m
3.Medium
t (s)v (m/s)3.75 s15

A car driving at 54 km/h brakes with a constant deceleration of 4 m/s² until it stops. Find the braking distance s.

v₀ = 54 km/ha = −4 m/s²v = 0
s = m
4.Medium
t (s)v (m/s)4.444 s22.22

A car driving at 80 km/h brakes with a constant deceleration of 5 m/s² until it stops. Find the braking distance s.

v₀ = 80 km/ha = −5 m/s²v = 0
s = 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. How long after the throw does it hit the ground? Find t.

v₀ = 18 m/sh₀ = 15 mg = 9.81 m/s²
t = s
6.Hard
d = ?

A stone is dropped from rest into a well. The splash is heard 4.9 s after the stone is released. The speed of sound is 343 m/s; ignore air resistance and use g = 9.81 m/s². Find the depth d of the well.

ttotal = 4.9 svsound = 343 m/sg = 9.81 m/s²
d = m

Answer key

  1. 1. s = 123.8 m
  2. 2. s = 225 m
  3. 3. s = 28.13 m
  4. 4. s = 49.38 m
  5. 5. t = 4.37 s
  6. 6. d = 103.7 m
