A small rock with mass 0.26 kg is released from rest at point A, which is at the top edge of a large, hemispherical bowl with radius R = 0.48 m (Figure 1). Assume that the size of the rock is small compared to R, so that the rock can be treated as a particle, and assume that the rock slides rather than rolls. The work done by friction on the rock when it moves from point A to point B at the bottom of the bowl has magnitude 0.22 J. Figure 1 of 1 Part A Between points A and B, how much work is done on the rock by the normal force? Express your answer in joules. Submit Request Answer Part B Between points A and B, how much work is done on the rock by gravity? Express your answer in joules. Submit Request Answer Part C What is the speed of the rock as it reaches point B ? Express your answer in meters per second. Submit Request Answer Part D Of the three forces acting on the rock as it slides down the bowl, which (if any) are constant? Check all that apply. None of the forces. Frictional force. Force due to gravity. Normal force. Part E Just as the rock reaches point B, what is the normal force on it due to the bottom of the bowl?

A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. During this proces5, what is the work done on the cabinet by its own weight, in Joule? Use g = 10.0 m/s2. Your answer noods to have 3 significant figures, inciuding the negative sign in your answer If needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

The work W done by a constant force F→ on an object that undergoes displacement s→ from point 1 to point 2 is W = F→⋅s→. For F in newtons (N) and s in meters (m), W is in joules ( J ). Part A If, during a displacement of the object, F→ has constant direction 60.0∘ above the −x-axis and constant magnitude 8.00 N and if the displacement is 0.800 m in the +x-direction, what is the work done by the force F→ ? Express your answer with the appropriate units.
