Question

Determine the launch speed of a horizontally launched projectile that lands 26.3m from the base of a 19.3m high cliff

Answer 1

The launch speed of a horizontally launched projectile is 13.28 m/s.

Time of motion of the projectile

The time of motion is calculated as follows;

t = √(2h / g)

where;

• h is height of the cliff
• g is acceleration due to gravity

t = √(2 x 19.3 / 9.8)

t = 1.98 s

Launch speed of the projectile

X = Vxt

Vx = X/t

Vx = (26.3)/(1.98)

Vx = 13.28 m/s

Thus, the launch speed of a horizontally launched projectile is 13.28 m/s.
