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. A gymnast jumps straight up, with her center of mass moving at 2.80 m/s as she leaves the ground. 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?
A 2004 Prius with a 150-lb driver and no passengers weighs 3071 lb. The car is initially at rest. Starting at t = 0, a net horizontal force Fx(t) in the +x direction is applied to the car. The force as a function of time is given in (Figure 1). The horizontal parts on the graph correspond to 7500 N and 3500 N. For the time interval t = 0 to t = 4.50 s, what is the impulse applied to the car? What is the speed of the car at t = 4.50 s? At t = 4.50 s, the 3500-N net force is replaced by a constant net braking force Bx = -5240 N . Once the braking force is first applied, how long does it take the car to stop? How much work must be done on the car by the braking force to stop the car? What distance does the car travel from the time the braking force is first applied until the car stops?

Valentina, a Russian cosmonaut, exits her ship for a space walk. When she is 15 m from the ship and floating motionless, her tether catches on a sharp piece of metal and is severed. Valentina quickly reacts by tossing her 2 kg camera away from the spaceship with a speed of 12 m/s. a). How fast will Valentina, whose combined mass with spacesuit is 188 kg, float toward the spaceship? (Round answer to nearest hundredth). b) Assuming that the space ship remains at rest with respect to her, How long (in seconds) will it take for her to float back to the ship ?

A block of mass m1 = 3.25 kg is connected to a second block of mass m2 = 1.85 kg , as shown in the figure.

Two ice skaters stand together as illustrated in Figure (a) below. They "push off" and travel directly away from each other, the boy with a velocity of v = 0.73 m/s to the left. If the boy weighs 701 N and the girl weighs 479 N, what is the girl's velocity after they push off? (Consider the ice to be frictionless. Enter the magnitude only.) m/s
