Calculate the magnitude of the force required to give a 0.145 kg baseball an acceleration a = 1.00 m/s2 in the direction of the baseball’s initial velocity when this velocity has a magnitude of (a) 10.0 m/s; (b) 0.900c; (c) 0.990c. (d) Repeat parts (a), (b), and (c) if the force and acceleration are perpendicular to the velocity
