Question

a tennis ball is tossed from the window of a building the ball is given an initial velocity of 8.0m/s at an angle of 30 degrees below the horizontal. it strikes the ground 4.5s later. how far horizontally from the base of the building does the ball strike the ground?

Expert Solution
Step 1: Equation of motion

A motion of an object or body when given some initial velocity with some angle from horizontal, is called projectile motion. The path followed by the object is parabola.  Projectile motion is 2 dimensional motion. There is only one force that works during the motion of an object, that is gravity which works downward.
