5086 9. A certain car's drive-train produces a force of 5300 N as it accelerates from 0 to 60 mph in 10.0 seconds. If this acceleration covers a distance of 125 m, determine the power output of the car's engine. va N₁ = 0 10. An engine moves a boat through the water at a constant speed of 15 m/s. The engine must develop a thrust of 6.0 KN to balance the force of drag from the water acting on the hull. Determine the power output of the engine. ✓ 11. An elevator's electric hoist is rated at 8.00 KW and has an efficiency of 90.0%. The hoist lifts the elevator car, mass 1225 kg, a distance of 9.00 m. (a) How much time is required? (b) How much electrical energy is used to perform this task? 12. Suppose a person uses a mechanical jack to lift half the weight of a car with a mass of 1200 kg. During each stroke of the jack handle, the person's hand is pushing for a distance of 40.0 cm but the car is lifted only 5.0 mm. (a) Assuming the jack is 100% efficient, how much force must the person exert on the handle as the car is lifted? (b) If the actual amount of force required on the handle is 90.0 N, what is the actual efficiency of the jack? 40cm=0.4m ↓ 5mm = 0.005m Answer: Amse to b. 140 m/s b. 288 kN 11. a. 15 s 12. a. 74 N 1. a. 250 MJ 2. a.-144 kJ 3. 2700 N 4. 26 mm03 5. a. 42 m/s (d) 6. -1200 J 7. a.
