1.Easy
h = 80 mv0​ = 25 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 = 25 m/sθ = 0°h = 80 mg = 9.81 m/s²
t = s
2.Easy
h = 35 mv0​ = 12 m/sx = ?

A ball is launched horizontally from the top of a 35 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v0 = 12 m/sθ = 0°h = 35 mg = 9.81 m/s²
x = m
3.Medium
v0​ = 22 m/s45°range

A ball is launched at 45° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v0 = 22 m/sθ = 45°g = 9.81 m/s²
t = s
4.Medium
v0​ = 26 m/s65°rangeH = ?

A ball is launched at 65° above horizontal from level ground. Ignore air resistance. Find the maximum height H the ball reaches.

v0 = 26 m/sθ = 65°g = 9.81 m/s²
H = m
5.Hard
h = 25 mv0​ = 12 m/s35°x = ?

A ball is launched at 35° above horizontal from the top of a 25 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v0 = 12 m/sθ = 35°h = 25 mg = 9.81 m/s²
x = m
6.Hard
h = 25 mv0​ = 19 m/s15°x = ?

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

v0 = 19 m/sθ = 15°h = 25 mg = 9.81 m/s²
x = m
