A block of mass 500 g is attached to a spring of spring constant 80 N/m as shown below. The other end of the spring is attached to a support while the mass rests on a rough surface with a coefficient of friction of 0.20 that is inclined at angle of 30∘. The block is pushed along the surface till the spring compresses by 10 cm and is then released from rest. (a) How much potential energy was stored in the block-spring-support system when the block was just released? (b) Determine the speed of the block when it crosses the point when the spring is neither compressed nor stretched. (c) Determine the position of the block where it just comes to rest on its way up the incline. (15 points)

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?
