1.Easy
t (s)v (m/s)3 sv = ?

A car moving at 4 m/s speeds up with a constant acceleration of 4 m/s² for 3 s. Find its final speed v.

v₀ = 4 m/sa = 4 m/s²t = 3 s
v = m/s
2.Easy
t (s)v (m/s)15 s9

A train slows down uniformly from 16 m/s to 9 m/s in 15 s. How far does it travel in that time? Find s.

v₀ = 16 m/sv = 9 m/st = 15 s
s = m
3.Medium
t (s)v (m/s)5.714 s20

A car driving at 72 km/h brakes with a constant deceleration of 3.5 m/s² until it stops. Find the braking distance s.

v₀ = 72 km/ha = −3.5 m/s²v = 0
s = m
4.Medium
a = ?s = 1100 m

A plane needs a speed of 200 km/h to take off and the usable runway is 1100 m long. Starting from rest, what constant acceleration a does it need?

v₀ = 0v = 200 km/hs = 1100 m
a = m/s²
5.Hard
AB: 30 m/s45 m

Ball A is dropped from rest from a height of 45 m. At the same instant ball B is thrown straight up from the ground directly below at 30 m/s. Ignore air resistance and use g = 9.81 m/s². At what height y above the ground do they meet?

H = 45 mv0B = 30 m/sg = 9.81 m/s²
y = m
6.Hard
v₀ = 16 m/s10 m

A ball is thrown straight up at 16 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 = 16 m/sh₀ = 10 mg = 9.81 m/s²
t = s

Answer key

  1. 1. v = 16 m/s
  2. 2. s = 187.5 m
  3. 3. s = 57.14 m
  4. 4. a = 1.403 m/s²
  5. 5. y = 33.96 m
  6. 6. t = 3.799 s
