1.Easy

A car moving at 12 m/s speeds up with a constant acceleration of 0.5 m/s² for 8 s. How far does it travel in that time? Find s.

v₀ = 12 m/sa = 0.5 m/s²t = 8 s

s = m

2.Easy

A train slows down uniformly from 11 m/s to 1 m/s in 17 s. How far does it travel in that time? Find s.

v₀ = 11 m/sv = 1 m/st = 17 s

s = m

3.Medium

A car speeding at a constant 21 m/s passes a police car standing still. At that moment the police car starts and accelerates uniformly at 5.5 m/s². How long does it take the police car to catch up? Find t.

v_car = 21 m/sa_police = 5.5 m/s²v_0,police = 0

t = s

4.Medium

A car speeding at a constant 24 m/s passes a police car standing still. At that moment the police car starts and accelerates uniformly at 2.5 m/s². How long does it take the police car to catch up? Find t.

v_car = 24 m/sa_police = 2.5 m/s²v_0,police = 0

t = s

5.Hard

A ball is thrown straight up at 14 m/s from the edge of a roof 5 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 = 14 m/sh₀ = 5 mg = 9.81 m/s²

t = s

6.Hard

A ball is thrown straight up at 8 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 = 8 m/sh₀ = 10 mg = 9.81 m/s²

t = s

Answer key

1. s = 112 m
2. s = 102 m
3. t = 7.636 s
4. t = 19.2 s
5. t = 3.175 s
6. t = 2.46 s
