1.Easy
t (s)v (m/s)7 s34.5

A car moving at 10 m/s speeds up with a constant acceleration of 3.5 m/s² for 7 s. How far does it travel in that time? Find s.

v₀ = 10 m/sa = 3.5 m/s²t = 7 s
s = m
2.Easy
t (s)v (m/s)11 s14

A train slows down uniformly from 21 m/s to 14 m/s in 11 s. How far does it travel in that time? Find s.

v₀ = 21 m/sv = 14 m/st = 11 s
s = m
3.Medium
t (s)v (m/s)3.03 s16.67

A car driving at 60 km/h brakes with a constant deceleration of 5.5 m/s² until it stops. Find the braking distance s.

v₀ = 60 km/ha = −5.5 m/s²v = 0
s = m
4.Medium
t (s)v (m/s)2.857 s20

A car driving at 72 km/h brakes with a constant deceleration of 7 m/s² until it stops. Find the braking distance s.

v₀ = 72 km/ha = −7 m/s²v = 0
s = m
5.Hard
v₀ = 7 m/s10 m

A ball is thrown straight up at 7 m/s from the edge of a roof 10 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 = 7 m/sh₀ = 10 mg = 9.81 m/s²
t = s
6.Hard
AB: 21 m/s15 m

Ball A is dropped from rest from a height of 15 m. At the same instant ball B is thrown straight up from the ground directly below at 21 m/s. Ignore air resistance and use g = 9.81 m/s². At what height y above the ground do they meet?

H = 15 mv0B = 21 m/sg = 9.81 m/s²
y = m

Answer key

  1. 1. s = 155.8 m
  2. 2. s = 192.5 m
  3. 3. s = 25.25 m
  4. 4. s = 28.57 m
  5. 5. t = 2.31 s
  6. 6. y = 12.5 m
