A block of mass M, at rest on a horizontal, frictionless table, is attached to a rigid support with a horizontal spring of force constant k. A bullet of mass m and velocity v parallel to the floor (and table) and collinear with the spring strikes the block. The bullet remains embedded in the block. Decide the amount of x that the spring is compressed, in terms of m, M, v, and k.
A car drives straight off the edge of a cliff that is 58 m high. The police at scene of the accident observed that the point of impact is 121m from the base of cliff. How fast was the car traveling when it went over the cliff.
A bat strikes a 0.145- baseball. Just before impact, the ball is traveling horizontally to the right at 40.0, and it leaves the bat traveling to the left at an angle of 30 above horizontal with a speed of 65.0. Find the vertical component of the a..
