A 45 kg box hangs from a rope. What is the tension in the rope if:(a) the box is at rest?(b) the box is rising with a constant velocity of 4.0 m/s?(c) the box is rising and speeding up at 4.5 m/s2?
Dave with a mass of 60 kg goes tubing down a 20 m long hill that has an angle off the horizon of 25º. (Gravity applies) a. He gets a push from the bottom of the hill, so his initial velocity is 2 m/s. How far up the hill will he go before stopping? (there’s no friction) b. He goes back down the hill and then his friend Jill tries to pull him on the tube across a small patch of grass (μk=0.30). If she is pulling parallel to the ground at constant 5 m/s for 5 sec how much power does she expend? c. After climbing back uphill, Dave decided to roll down the hill instead. If he were to be a long cylinder with a radius of 0.1 m, what is his moment of inertia? d. After rolling without slipping down the hill, what is Dave’s final velocity at the bottom of the hill? What is his angular velocity at the bottom of the hill? Dave with a mass of 60 kg goes tubing down a 20 m long hill that has an angle off the horizon of 25º. (Gravity applies) He gets a push from the bottom of the hill, so his…
