A 3.67 g bullet is fired vertically into a 1.61 kg block of wood. The bullet gets stuck in the block, and the impact lifts the block 0.071 m up. (That is, the block with the bullet stuck in it rises 0.071 m up above its initial position, and then falls back down.) Given g = 9.8 m/s2
What was the initial velocity of the bullet?
During a drive by golfer Tiger Woods, the angular velocity of his club is zero at the top of the backswing and the 1719 degree/second at the bottom of the downswing just before impact with the ball
An atomic nucleus of mass m travelling with speed v collides elastically with a target particle of mass 2.000m (at first at rest) and is scattered at 90.
An aircraft performs a maneuver called an aileron roll. During this maneuver, the plane turns like a screw as it maintains a straight flight path, which is the acceleration of the wing tip
A bat at rest sends out ultrasonic sound waves at 50.5 kHz and receives them returned from an object moving directly away from it at 30.5 m/s
