Review. A student performs a ballistic pendulum experiment using an apparatus similar to that discussed in Example 9.6 and shown in Figure P9.36. She obtains the following average data: h = 8.68 cm, projectile mass m1 = 68.8 g, and pendulum mass m2 = 263 g. (a) Determine the initial speed v1A of the projectile. (b) The second part of her experiment is to obtain v1A by firing the same projectile horizontally (with the pendulum removed from the path) and measuring its final horizontal position x and distance of fall y (Fig. P9.43). What numerical value does she obtain for v1A based on her measured values of x = 257 cm and y = 85.3 cm? (c) What factors might account for the difference in this value compared with that obtained in part (a)?

You are lawn bowling and bowl a 540 g ball with a speed of 6.15 m/s. Unfortunately, your ball hits a large rock, resulting in a perfectly elastic collision. If the final velocity of the rock after the collision is 2.13 m/s, what must the mass of the rock be? a) 0.0330 kg b) 0.240 kg c) 0.540 kg d) 2.58 kg

During a circus act, a performer thrills the crowd by catching a cannon ball shot at him. The cannon ball has a mass of m1 = 8.5 kg and the horizontal component of its velocity is v = 8.25 m/s when the performer, of mass m2 = 70.5 kg, catches it. a)If the performer is on nearly frictionless roller skates, enter an expression for his recoil speed, in terms of the masses and initial speed. v' =
