You are part of a team in an engineering class that is working on a scale model of a new design for a life vest. You have been asked to find the mass of a piece of foam that will be used for flotation. Because the piece is too bulky to fit on your balance, you break it into two parts. You measure the mass of the first part as 128.3 0.3 g and the second part as 77.0 0.3 g. a. What are the maximum and minimum values for the total mass you might reasonably report? b. What is the best estimate for the total mass of the foam? Hint: Propagation of uncertainty is described in Appendix A.
A 60-kg soccer player jumps vertically upwards and heads the 0.45-kg ball as it is descending vertically with a speed of 25 m/s. (a) If the player was moving upward with a speed of 4.0 m/s just before impact, what will be the speed of the ball immediately after the collision if the ball rebounds vertically upwards and the collision is elastic? (b) If the ball is in contact with the players head for 20 ms, what is the average acceleration of the ball? (Note that the force of gravity may be ignored during the brief collision time.)
In Example 2.12, two circus performers rehearse a trick in which a ball and a dart collide. We found the height and time of the collision graphically. Return to that example, and find height and time by simultaneously solving the equations for the ball and the dart.
A flying squid (family Ommastrephidae) is able to jump off the surface of the sea by taking water into its body cavity and then ejecting the water vertically downward. A 0.850-kg squid is able to eject 0.300 kg of water with a speed of 20.0 m/s. (a) What will be the speed of the squid immediately after ejecting the water? (b) How high in the air will the squid rise?
In a head-on, inelastic collision, a 4,000-kg truck going 10 m/s east strikes a 1,000-kg car going 20 m/s west. (a) What is the speed and direction of the wreckage? (b) How much kinetic energy was lost in the Collision?
Alex throws a 0.15-kg rubber ball down onto the floor. The ball's speed just before impact is 4.5 m/s, and just after is 2.5 m/s.

18. Auto companies frequently tests the safety of the automobiles by putting them through crash tests to observe the integrity of the passenger compartment. If a 1000 kg car is sent down a cement wall with a speed of 14 m/s and the impact brings it to a stop in 8.00 x 10^-2 s, with what average force is it brought to rest? *Use g=9.8 a. 145 000 N b. 212 000 N c. 315 000 N d. 175 000 N e. 423 000 N
A 2.00-kg (20.0-N) stone is dropped from a height of 5.0 m, and strikes the ground with a velocity of 8.00 m/s. As the stone falls, it is acted on by force from air friction. What is the average force that air friction exerted on the stone? A. 1.6 N B. 3.2 N C. 7.2 N D. 10.0 N E. 20.0 N
14. mmh A golf club strikes a 0.045-kg golf ball in order to launch it from the tee. For simplicity, assume that the average net force applied to the ball acts parallel to the ball's motion, has a magnitude of 6800 N, and is in contact with the ball for a distance of 0.010 m. With what speed does the ball leave the club?
