1.Easy
t (s)v (m/s)6 sv = ?

A car moving at 12 m/s speeds up with a constant acceleration of 0.5 m/s² for 6 s. Find its final speed v.

v₀ = 12 m/sa = 0.5 m/s²t = 6 s
v = m/s
2.Easy
t (s)v (m/s)5 sv = ?

A car moving at 8 m/s speeds up with a constant acceleration of 1.5 m/s² for 5 s. Find its final speed v.

v₀ = 8 m/sa = 1.5 m/s²t = 5 s
v = m/s
3.Medium
t (s)v (m/s)2.308 s15

A car driving at 54 km/h brakes with a constant deceleration of 6.5 m/s² until it stops. Find the braking distance s.

v₀ = 54 km/ha = −6.5 m/s²v = 0
s = m
4.Medium
t (s)v (m/s)1.1 s22.22

A driver moving at 80 km/h sees an obstacle. Her reaction time is 1.1 s, after which the car brakes with a constant deceleration of 4 m/s². Find the total stopping distance d from the moment she sees the obstacle.

v₀ = 80 km/htr = 1.1 sa = −4 m/s²
d = m
5.Hard
t (s)v (m/s)5 s

A tram starts from rest and accelerates at 1 m/s² for 5 s, then runs at constant speed for 22 s, and finally brakes at 2 m/s² until it stops. Find the total distance s between the two stops.

a1 = 1 m/s²t1 = 5 st2 = 22 sa3 = −2 m/s²
s = m
6.Hard
t (s)v (m/s)6 s

A tram starts from rest and accelerates at 2.5 m/s² for 6 s, then runs at constant speed for 15 s, and finally brakes at 3 m/s² until it stops. Find the total distance s between the two stops.

a1 = 2.5 m/s²t1 = 6 st2 = 15 sa3 = −3 m/s²
s = m

Answer key

  1. 1. v = 15 m/s
  2. 2. v = 15.5 m/s
  3. 3. s = 17.31 m
  4. 4. d = 86.17 m
  5. 5. s = 128.8 m
  6. 6. s = 307.5 m
