Question

A physics student stands on a cliff overlooking a lake and decides to throw a softball to her friends in the water below. She throws the softball with a velocity of 22.5 m/s22.5 m/s at an angle of 39.5∘39.5∘ above the horizontal. When the softball leaves her hand, it is 15.5 m15.5 m above the water. How far does the softball travel horizontally before it hits the water? Neglect any effects of air resistance when calculating the answer.

Step 1

__Given:__

Velocity of ball thrown, u = 22.5 m/s

Initial height of the ball above the water, H = 15.5 m

Angle of projection, θ = 39.5^{o}

Step 2

Calculating the time taken by the ball to reach to the water:

Step 3

Calculating the horizontal distance travelled b...
