Water drives a waterwheel (or turbine) of radius R = 3.0 m as shown in Fig. 8–66. The water enters at a speed vi = 7.0 m/s and exits from the waterwheel at a speed v2 = 3.8 m/s. (a) If 85 kg of water passes through per second, what is the rate at which the water delivers angu- lar momentum to the waterwheel? (b) What is the torque the water applies to the waterwheel? (c) If the water causes the waterwheel to make one revolution every 5.5 s, how much power is delivered to the wheel? FIGURE 8–66 Problem 95.

A projectile of mass 2.0 kg is fired in the air at an angle of 40.0 to the horizon at a speed of 50.0 m/s. At the highest point in its flight, the projectile breaks into three parts of mass 1.0 kg, 0.7 kg, and 0.3 kg. The 1.0-kg part falls straight down after breakup with an initial speed of 10.0 m/s, the 0.7-kg part moves in the original forward direction, and the 0.3-kg part goes straight up. Launch a. Find the speeds of the 0.3-kg and 0.7-kg pieces immediately after the break-up. b. How high from the break-up point does the 0.3-kg piece go before coming to rest? c. Where does the 0.7-kg piece land relative to where it was fired from?
Two billiard balls meet centrally with speeds of 2 and -4 m/s. What will be their final speeds after the impact if the coefficient of restitution is 0.83?
The total linear momentum of a system can be zero, even if all the objects in the system are moving. True or false?

During world war 2, a military parachutist fell 0.37km from an airplane without being able to open his chute, but luckily was able to land in snow, suffering only with minor injuries. Assume that his speed at impact was 56m/s, and his mass, including his gear was 85kg, and that the magnitude of force on him from the snow was at the survivable limit of 1.2 x 10^5 N. What is the magnitude of the impulse on him from the snow? (Answer in one decimal place, no unit) sample answer: 1.1 x 10^3 (enter the 1.1 only)
Can you produce a net impulse on an automobile by sitting inside and pushing on the dashboard? Can the internal forces within a soccer ball produce an impulse on the soccer ball that will change its momentum?
In a perfect inelastic collision, the momentum is conserved even though the KE of the colliding body decreases. Explain.
A soccer ball has a mass of 0.40 kg. Initially, it is moving to the left at 20 m/s, but then, it is kicked and given a velocity at 45º upward and to the right, with a magnitude of 30 m/s.Find the impulse of the net force and the average net force, assuming a collision time (∆t = 0.01 s)
A person is pushing a 8 kg block along a horiontal surface at a constant speed of 15.4 m/s. The person is applying a force of 8.9 N to the block at an angle of 36.7° above horizontal.
