Two blocks, of masses m1 and m2, are connected by a model string. Both blocks lie on a plane that is inclined to the horizontal at an angle [symbol1]. The part of the plane supporting the block of mass m1 is smooth, so that there is no frictional force. The upper part of the plane is rough, as that coefficient of the static fric

The Impulse Momentum Theorum for baseball: what is the average force exerted on the ball by the bat?
A baseball (m = 149 g ) approaches a bat horizontally at a speed of 40.2 m/s (90 mi/h) and is hit straight back at a speed of 45.6 m/s (102 mi/h). If the ball is in contact with the bat for a time of 1.10 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the ball, since it is so much less than t
