Step 1

Given information:

Speed of the receiver (vr) = 5.50 m/s

Angle at which the ball is thrown (θ) = 250

The distance of the receiver from the throw (d) = 10.00 m

Step 2

Let “T” be the time spent by the ball in air, then the horizontal distance travelled by the ball in this time is given by:

Step 3

The total time of flight is g...
