1.Easy
h = 35 mv0​ = 10 m/srange

A ball is launched horizontally 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 = 0°h = 35 mg = 9.81 m/s²
t = s
2.Easy
h = 80 mv0​ = 15 m/sx = ?

A ball is launched horizontally from the top of an 80 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v0 = 15 m/sθ = 0°h = 80 mg = 9.81 m/s²
x = m
3.Medium
v0​ = 28 m/s25°range

A ball is launched at 25° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v0 = 28 m/sθ = 25°g = 9.81 m/s²
t = s
4.Medium
v0​ = ?15°R = 100 m

A ball is launched from level ground at 15° above the horizontal and lands 100 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v0.

θ = 15°R = 100 mg = 9.81 m/s²
v0 = m/s
5.Hard
h = 55 mv0​ = 10 m/s20°x = ?

A ball is launched at 20° above horizontal from the top of a 55 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v0 = 10 m/sθ = 20°h = 55 mg = 9.81 m/s²
x = m
6.Hard
h = 60 mv0​ = 30 m/s35°range

A ball is launched at 35° above horizontal from the top of a 60 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v0 = 30 m/sθ = 35°h = 60 mg = 9.81 m/s²
t = s

Answer key

  1. 1. t = 2.671 s
  2. 2. x = 60.58 m
  3. 3. t = 2.412 s
  4. 4. v0 = 44.29 m/s
  5. 5. x = 34.91 m
  6. 6. t = 5.667 s
