In 1971 astronaut Alan Shepard took a golf club to the Moon, where the acceleration due togravity is about g/6. If he struck a ball with the a speed and launch angle that would result ina maximum 120m horizontal range on Earth, how far would it go?
Jessica's weight is 540 newtons. According to the Third Law, if the Earth pulls on Jessica with a force of 540 N, then Jessica pulls on the Earth with a force of 540 newtons that acts in the opposite direction.though , if Jessica stumbles while rol..
