Physics I. Unit : potential energy and conservation of energy. A,B,C, please In the figure, a 3.9 kg block is accelerated from rest by a compressed spring of spring constant 630 N/m. The block leaves the spring at the spring's relaxed length and travels over a horizontal floor with a coefficient of kinetic friction mu_k = 0.215. The frictional force stops the block in distance D = 7.7 m. What are (a) the increase in the thermal energy of the...
1a. 1b. In the figure below, a block slides along a track from one level to a higher level after passing through an intermediate valley.

Solve Part D please Learning Goal: To understand how the conservation of energy and Newton's second law can be combined to solve kinetic problems. As shown, a large globe has a radius R and a frictionless surface. A small block with mass m starts sliding from rest at the top of the globe and slides along the globe's surface. The block leaves the globe's surface when it reaches a height h above the ground. The system's geometry is shown for...
Where's the Energy? Need help with concepts in the problem below! In this problem, we will consider the following situation as depicted in the diagram (Figure 1) : A block of mass m slides at a speed v along a horizontal, smooth table. It next slides down a smooth ramp, descending a height h, and then slides along a horizontal rough floor, stopping eventually. Assume that the block slides slowly enough so that it does not lose contact with the...
1. A block of mass m = 0.23 kg slides with initial velocity v0 = 1.4 m/s along a frictionless surface (as in the figure). The block next slides through a region of length d = 0.25 m with kinetic friction. After passing through the friction region, the block slides up a curved ramp until momentarily coming to rest at a height h above the level surface. If the kinetic friction coefficient μ k = 0.204, what height h does...
