A block of mass m = 4,70 kg is released from rest from point and slides on the frictionless track shown in the figure below. (Assume h = 7.50 m.) 3.20 m 2.00 m (a) Determine the block's speed at points 9 and O point U m/s point G m/s (b) Determine the net work done by the gravitational force on the block as it moves from point to point

A 15.1-kg box is being pushed from the bottom to the top of a frictionless ramp. When the box is pushed at a constant velocity, the nonconservative pushing force does 58.0 J of work. How much work is done by the pushing force when the box starts from rest at the bottom and reaches the top of the same ramp with a speed of 1.50 m/s? Wnc = Number i Units

The force F(x) varies with position, as shown below. Find the work done by this force on a particle as it moves from x = 1.0 m to x = 5.0 m. F(x) (N) 4 6.0 4.0 2.0 0 -2.0 -4.0 2.0 4.0 6.0 8.0 x(m)

A box of mass 4.0 kg hangs by a cable from the ceiling of an elevator. The elevator is moving down at a steady speed of 5.0 m/s for 8.0 m. Use g = 10 m/s2. Match the answers with questions. he work done on the box by its weight (WW)                                                                        the work done on the box by the tension force in the cable  (WT)                                                                        the net work done on the box  (Wnet) A. 0 J B. 50 J C. 320 J D. -50 J E. -320 J
