q4 A 25-kg block on a horizontal surface is attached to a light spring (force constant = 8.0 kN/m). The block is pulled 10 cm to the rightfrom its equilibrium position and released from rest. When the block has moved 2.0 cm toward its equilibrium position, its kineticenergy is 12 J. What is the change in mechanical energy caused by the frictional force on the block as it moves the 2.0 cm?A) -4.0 JB) -3.5 Jc) -2.4 JD) -2.9 J(E) -15 J

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.
