1.Easy
v0​ = 22 m/s65°t = ?

A ball is kicked from level ground at 22 m/s and 65° above the horizontal. Ignore air resistance and use g = 9.81 m/s². How long t after the kick does it reach its highest point?

v₀ = 22 m/sθ = 65°g = 9.81 m/s²
t = s
2.Easy
h = 60 mv0​ = ?x = 57 m

A stone is thrown horizontally from the top of a 60 m high wall and lands 57 m from the foot of the wall. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v0.

h = 60 mx = 57 mg = 9.81 m/s²
v0 = m/s
3.Medium
v0​ = 12 m/s70°range

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 = 12 m/sθ = 70°g = 9.81 m/s²
t = s
4.Medium
v0​ = 18 m/s35°range

A ball is launched at 35° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v0 = 18 m/sθ = 35°g = 9.81 m/s²
t = s
5.Hard
h = 35 mv0​ = 10 m/s30°range

A ball is launched at 30° above horizontal from the top of a 35 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v0 = 10 m/sθ = 30°h = 35 mg = 9.81 m/s²
t = s
6.Hard
h = 40 mv0​ = 15 m/s45°range

A ball is launched at 45° above horizontal from the top of a 40 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v0 = 15 m/sθ = 45°h = 40 mg = 9.81 m/s²
t = s

Answer key

  1. 1. t = 2.032 s
  2. 2. v0 = 16.3 m/s
  3. 3. t = 2.299 s
  4. 4. t = 2.105 s
  5. 5. t = 3.229 s
  6. 6. t = 4.135 s
