Homework Statement
A student is riding in the back of a truck traveling along a straight level road at Vt = 20 m/s. He faces toward the rear of the truck and throws a ball with a velocity of 15 m/s at an angle of 37 degrees above the horizontal relative to the truck. He releases the ball 2.0 meters above the ground level. Ignore air resistance.
What is the horizontal velocity of the ball relative to an observer at roadside?
The Attempt at a Solution
I don't even know where to start this.
I am assuming I need to find the balls horizontal velocity and subtract it from the initial 20 m/s since the student threw the ball in the opposite direction. Then figure out the horizontal velocity relative to the observer...
