A 500. g mass is attached to the end of a 1.45 m string. You hold the mass so that the 2) string makes an angle of 25.0° with the vertical before releasing it from rest. The mass then collides with a stationary 750.g mass at the very bottom of the swing. Immediately after the collision, the second mass is moving at 1.15 m/s. a) How fast, and in what direction is the mass on the string moving immediately after the collision? b) Is this an elastic or inelastic collision? c) How much, if any, kinetic energy is dissipated during this collision?

A 2.00-kg object hangs, at rest, on a 1.00-m-long string attached to the ceiling. A 100-g mass is fired with a speed of 20 m/s at the 2.00-kg mass, and the 100.00-g mass collides perfectly elastically with the 2.00-kg mass. Write an equation for the motion of the hanging mass after the collision. Assume air resistance is negligible.
To promote his new single “Itaktak Mo”, Joe decided to launch a satellite into orbit that will intercept allairwaves and play his song worldwide. To do this, he needs to mount his 100 [kg] satellite onto a 750 [kg]rocket. It blasts off vertically from a launch pad with a constant net upward acceleration of 3.80 [m/s2].When it has reached a height of 680 [m], the satellite was released, and the rocket blew up shortly after,due to a system failure. Assume that the satellite was not damaged after the explosion. A. What is the maximum height that the satellite will reach above the launch pad? B. How much time will elapse after system failure before the satellite comes crashing down the launchpad? C. How fast will the satellite be moving just before it crashes?

In Chapter 9, we will define the center of mass of an object and prove that its motion is described by the particle under constant acceleration model when constant forces act on the object.

How high above this point is her center of mass (a) 0.100 s, (b) 0.200 s, (c) 0.300 s. and (d) 0.500 s thereafter?

Does the kinetic energy of an object depend on the frame of reference in which its motion is measured? Provide an example to prove this point.
An object of mass m is suspended from the top of a cart by a string of length L as in Figure P5.88a. The cart and object are initially moving to the right at a constant speed 0. The cart comes to rest after colliding and sticking to a bumper, as in Figure P5.88b, and the suspended object swings through an angle . (a) Show that the initial speed is 0=2gL(1cos). (b) If L = 1.20 m and = 35.0, find the initial speed of the cart (Hint: The force exerted by the string on the object docs no work on the object.) Figure P5.88a
