Part A: Calculate the magnitude of the force required to give a 0.145-kg baseball an acceleration a=1.00m/s² in the direction of the baseball's initial velocity when this velocity has a magnitude of 10.0m/s.

Part B: Calculate the magnitude of the force required to give a 0.145-kg baseball an acceleration a=1.00m/s2 in the direction of the baseball's initial velocity when this velocity has a magnitude of 0.900c.

Part C: Calculate the magnitude of the force required to give a 0.145-kg baseball an acceleration a=1.00m/s2 in the direction of the baseball's initial velocity when this velocity has a magnitude of 0.990c.

Part D: Repeat part A if the force and acceleration are perpendicular to the velocity.

Part E: Repeat part B if the force and acceleration are perpendicular to the velocity.

Part F: Repeat part C if the force and acceleration are perpendicular to the velocity.
