You are bowling and have one pin left standing. You roll the 10kg bowling ball at a velocity of +1 m s into the 1kg pin, which is at rest. After the ball hits the pin, the pin and the ball both travel along a straight line. If the ?nal velocity of the ball after it hits the pin is +0.9 m s what is the kinetic energy of the pin after it is struck by the ball?
A chair of weight 130 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 43.00 N directed at the angle of 35.0 degrees below the horizontal and the chair slides along the floor. Using Newton's law..
