Question

A ball is thrown horizontally from the top of a 53.0-m building and lands 119.3 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.)

a) How long (in s) is the ball in the air? in s

b) What must have been the initial horizontal component of the velocity (in m/s)? (Indicate the direction with the sign of your answer.) in m/s

c) What is the vertical component of the velocity (in m/s) just before the ball hits the ground? (Indicate the direction with the sign of your answer.) in m/s

d) What is the velocity (in m/s) (including both the horizontal and vertical components) of the ball just before it hits the ground?

magnitude in m/s

direction in ()° counterclockwise from the +x-axis
