An 0.8kg baseball with an initial velocity of 40m/s is hit with a baseball bat so that its recoil velocity is 60m/s in the exact opposite direction. what is the average force the bat puts on the ball
A 54 {rm kg} ice skater spins about a vertical axis through her body with her arms horizontally outstretched, making 2.5 turns each second. The distance from one hand to other is 1.5 {rm m}. Biometric measurements indicate that each hand typically..
A string is wrapped around the disk of mass m = 1.8 kg and radius R = 0.11 m. Starting from rest, you pull the string with a constant force F = 8 N along the nearly frictionless surface. At an instant when the center of the disk has moved a distan..
