1.Easy
h = 80 mv0​ = 22 m/srange

A ball is launched horizontally from the top of an 80 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v0 = 22 m/sθ = 0°h = 80 mg = 9.81 m/s²
t = s
2.Easy
h = 50 mv0​ = 15 m/sv = ?

A ball is thrown horizontally at 15 m/s from the top of a 50 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 15 m/sh = 50 mg = 9.81 m/s²
v = m/s
3.Medium
v0​ = 16 m/s65°range

A ball is launched at 65° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v0 = 16 m/sθ = 65°g = 9.81 m/s²
t = s
4.Medium
v0​ = 30 m/s20°rangeH = ?

A ball is launched at 20° above horizontal from level ground. Ignore air resistance. Find the maximum height H the ball reaches.

v0 = 30 m/sθ = 20°g = 9.81 m/s²
H = m
5.Hard
h = 50 mv0​ = 10 m/s60°range

A ball is launched at 60° above horizontal from the top of a 50 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v0 = 10 m/sθ = 60°h = 50 mg = 9.81 m/s²
t = s
6.Hard
h = 10 mv0​ = 24 m/s20°x = ?

A ball is launched at 20° above horizontal from the top of a 10 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v0 = 24 m/sθ = 20°h = 10 mg = 9.81 m/s²
x = m

  1. 1. t = 4.039 s
  2. 2. v = 34.73 m/s
  3. 3. t = 2.956 s
  4. 4. H = 5.366 m
  5. 5. t = 4.195 s
  6. 6. x = 56.19 m
