- 4. A 3000 lb elevator is supported by a 14 ft cable that weighs 15 lbs/ft. Find the work required to lift the elevator 12 feet by winding the cable. (Hint: Calculate the work required to pull the rope up, then add the work required for the elevator.)What is the power rating of a motor that is capable of lifting a 100 kg object to a height of 20 m in one minute? (hint: watch your units) a 33 W b 19600 W c 327 W d 2000 WWhat is the power done by gravity to make a ball of mass 0.68 kg roll from 1.3 m above the ground to the bottom along a curved path if it takes 2.68s to do so?
- 45. Suppose a person uses a mechanical jack to lift one 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?Consider a hoop of mass 3.1 kg and radius 0.52 m that rolls without slipping down an incline. The hoop starts at rest from a height h = 2.7 m above the bottom of the incline and then rolls to the bottom.Find the veloclty of the bucket with a mass of m = 2.00 kg attached pulley with a mass of M = 3.00 kg and a radlus of R = 0.400 m after It has dropped (2.67x10^1) meters.
