1.Easy

A car moving at 8 m/s speeds up with a constant acceleration of 2 m/s² for 11 s. How far does it travel in that time? Find s.

v₀ = 8 m/sa = 2 m/s²t = 11 s

s = m

2.Easy

A car moving at 10 m/s speeds up with a constant acceleration of 1.5 m/s² for 12 s. How far does it travel in that time? Find s.

v₀ = 10 m/sa = 1.5 m/s²t = 12 s

s = m

3.Medium

A driver moving at 36 km/h sees an obstacle. Her reaction time is 1.2 s, after which the car brakes with a constant deceleration of 6.5 m/s². Find the total stopping distance d from the moment she sees the obstacle.

v₀ = 36 km/ht_r = 1.2 sa = −6.5 m/s²

d = m

4.Medium

A driver moving at 60 km/h sees an obstacle. Her reaction time is 0.9 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 = 60 km/ht_r = 0.9 sa = −4 m/s²

d = m

5.Hard

A ball is thrown straight up at 12 m/s from the edge of a roof 15 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 = 12 m/sh₀ = 15 mg = 9.81 m/s²

t = s

6.Hard

A ball is thrown straight up at 6 m/s from the edge of a roof 5 m above the ground. Ignore air resistance and use g = 9.81 m/s². Find the greatest height h_max above the ground.

v₀ = 6 m/sh₀ = 5 mg = 9.81 m/s²

h_max = m

Answer key

1. s = 209 m
2. s = 228 m
3. d = 19.69 m
4. d = 49.72 m
5. t = 3.357 s
6. h_max = 6.835 m
