1.Easy
v0​ = 16 m/s30°t = ?

A ball is kicked from level ground at 16 m/s and 30° 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 = 16 m/sθ = 30°g = 9.81 m/s²
t = s
2.Easy
h = 20 mv0​ = 18 m/srange

A ball is launched horizontally from the top of a 20 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v0 = 18 m/sθ = 0°h = 20 mg = 9.81 m/s²
t = s
3.Medium
v0​ = 32 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 = 32 m/sθ = 70°g = 9.81 m/s²
t = s
4.Medium
v0​ = 28 m/s60°rangeH = ?

A ball is launched at 60° above horizontal from level ground. Ignore air resistance. Find the maximum height H the ball reaches.

v0 = 28 m/sθ = 60°g = 9.81 m/s²
H = m
5.Hard
h = 20 mv0​ = 33 m/s15°x = ?

A ball is launched at 15° above horizontal from the top of a 20 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v0 = 33 m/sθ = 15°h = 20 mg = 9.81 m/s²
x = m
6.Hard
h = 50 mv0​ = 17 m/s20°x = ?

A ball is launched at 20° above horizontal from the top of a 50 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v0 = 17 m/sθ = 20°h = 50 mg = 9.81 m/s²
x = m
