1.Easy

A ball is launched horizontally from the top of a 10 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 15 m/sθ = 0°h = 10 mg = 9.81 m/s²

t = s

2.Easy

A ball is thrown horizontally at 6 m/s from the top of a 45 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 6 m/sh = 45 mg = 9.81 m/s²

v = m/s

3.Medium

A ball is launched at 70° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 36 m/sθ = 70°g = 9.81 m/s²

t = s

4.Medium

A ball is kicked from level ground at 38 m/s and 65° above the horizontal towards a wall 34 m away. Ignore air resistance and use g = 9.81 m/s². At what height y does the ball pass the wall?

v₀ = 38 m/sθ = 65°x = 34 mg = 9.81 m/s²

y = m

5.Hard

A ball is launched at 25° above horizontal from the top of a 15 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 25 m/sθ = 25°h = 15 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 25° above horizontal from the top of a 60 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 19 m/sθ = 25°h = 60 mg = 9.81 m/s²

x = m

Answer key

1. t = 1.428 s
2. v = 30.31 m/s
3. t = 6.897 s
4. y = 50.93 m
5. x = 70.94 m
6. x = 75.95 m
