Answer 1

Answer #1

From the law of conservation of energy, mgh+Wan = mv The work done by air resistance is W. =-- mv2 = mgh kg)(8.5 m/s)-(0.500

A ball with a mass of 327 oz. is dropped down vertically from a height of 1.31 m. The speed right before the ball hit the ground was measured to be 14.5 ft/s. Assuming that the force due to air resistance is constant (and non-zero), what is the magnitude of this force? The initial velocity of the ball is zero. The direction of the force due to the air resistance is opposite to the direction that the ball is moving....
