A 52.4-gram ball is thrown from the ground into the air, with an initial speed of 16.3 m/s at an angle of 27.4o above the horizontal, Find the values of the kinetic energy of the ball initially and just before it hits the ground? Determine the corresponding values of the momentum (direction and magnitude) and the change in momentum, Show that the change in momentum is equal to the weight of the ball multiplied by the time of flight, and thereby determine the time of flight.
