Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

5. 1) As shown in the image below, the snowmobile has a weight of 259 lb, centered at G1, while the rider has a weight of 154 Ib, centered at G2. If the acceleration is a = 13.5 ft/s?, dimensions are di = 0.9 ft, d2 = 0.4 ft, d3 = 1.6 ft, d4 = 1.6 ft, and height h of G2 of the rider is 1.8 ft, determine the normal reaction force under the front skid at point B. Assume there is only traction (horizontal) force under the rear tracks, but no friction force under the front skid. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take g= 32.2 ft/s2. a G2 G1 h A В dz da -

3. A 5-kg crate is released from rest at Point A of a 20-kg ramp which is inclined at 40 degrees as shown in the figure below. The lengths of the ramp is 2 m. The interface between the ramp and the ground can be assumed to be frictionless. Use Newton's 2nd Law and the definition of the center of mass to determine the horizontal distance that the ramp has moved when the crate reaches Point B. Neglect the size of the crate. Does your answer depend on the frictional force between the crate and the ramp? e S
