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
4 Problem Consider a slider, modeled as a particle P of mass m, moving along a frictionless shaft. The slider moves in the horizontal plane (there is no gravity). At the instant shown, the speed of the slider is v, and the spring is stretched to length r>lo, where lo is its unstretched length. The spring forms an angle 0 as shown and the spring constant k is unknown. If, at the instant shown, 0 = 0 and r = 0 in the polar frame then what must the spring constant be? Also determine the normal force at this instant. Express both in terms of one or more of the following variables: (v, m,r,lo,0). (Hint: first solve for r and from the velocity kinematics.)
