    Change in momentum of baseball being struck

    Homework Statement A 0.33 kg softball has a velocity of 14 m/s at an angle of 50° below the horizontal just before making contact with the bat. What is the magnitude of the change in momentum of the ball while it is in contact with the bat if the ball leaves the bat with a velocity of (a) 15...

    Frictional Forces and Two dimensional constant acceleration problem

    1. The floor of a railroad flatcar is loaded with loose crates having a coefficient of static friction of 0.36 with the floor. If the train is initially moving at a speed of 42 km/h, in how short a distance can the train be stopped at constant acceleration without causing the crates to slide...
