1. Grant accelerates a baseball (m= 0.145 kg) 20 m/s² horizontally. The vertical acceleration of the ball is zero in this interest. The force of gravity is the only external force acting on the ball other than the forces Grant exerts on it. a. Draw a free body diagram of the ball. b. How large is the horizontal force Grant exerts on the ball at this instant to cause its 20m/s² horizontal acceleration? c. How large is the vertical force Grant exerts on the ball at this instant?
