1.Easy
t (s)v (m/s)10 s25

A car moving at 10 m/s speeds up with a constant acceleration of 1.5 m/s² for 10 s. How far does it travel in that time? Find s.

v₀ = 10 m/sa = 1.5 m/s²t = 10 s
s = m
2.Easy
t (s)v (m/s)7 s15.5

A car speeds up uniformly from 12 m/s to 15.5 m/s in 7 s. Find the acceleration a.

v₀ = 12 m/sv = 15.5 m/st = 7 s
a = m/s²
3.Medium
t (s)v (m/s)3.704 s22.22

A car driving at 80 km/h brakes with a constant deceleration of 6 m/s² until it stops. Find the braking distance s.

v₀ = 80 km/ha = −6 m/s²v = 0
s = m
4.Medium
t (s)v (m/s)t = ?33.33

A car driving at 120 km/h brakes with a constant deceleration of 4.5 m/s² until it stops. How long does braking take? Find t.

v₀ = 120 km/ha = −4.5 m/s²v = 0
t = s
5.Hard
v₀ = 13 m/s20 m

A ball is thrown straight up at 13 m/s from the edge of a roof 20 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 = 20 mg = 9.81 m/s²
t = s
6.Hard
t (s)v (m/s)8 s

A tram starts from rest and accelerates at 2.5 m/s² for 8 s, then runs at constant speed for 24 s, and finally brakes at 4 m/s² until it stops. Find the total travel time t.

a1 = 2.5 m/s²t1 = 8 st2 = 24 sa3 = −4 m/s²
t = s

Answer key

  1. 1. s = 175 m
  2. 2. a = 0.5 m/s²
  3. 3. s = 41.15 m
  4. 4. t = 7.407 s
  5. 5. t = 3.74 s
  6. 6. t = 37 s
