- 8) A 60.0 kg student starts from rest (Point A) and slides 26.0 m down a hill where the average force of friction is 55.0 N. What is her final speed at the bottom of the hill (Point B) if the vertical drop is 17.0 m? 17.0 m 26.0 m B4. Here we prove a version of the work-kinetic energy theorem for an object moving in 1-D subject to a constant force. Consider a mass m, traveling initially at speed v, on which a constant net force F is applied in the same direction as its motion over a distance d. After the net force has acted over this distance, the speed of the object is v2. In terms of m, F, v1, v2, and d only, V, A) What is the acceleration of the mass? t=0 m F d t>0_m B) What is the time over which the mass travels the V, distance d? [Use one equation of constant acceleration to find this.] C) Use another equation of constant acceleration to relate m, F, v,, v2, and d. Show that the product W = Fd is equal to the change in the mass’s kinetic energy.3. A body loses 5693 J of potential energy in falling through 65.5 m. Calculate the mass of the body.
