Question

8 and 9

ull tle D1ek and surface is 0.20. but the energy equation between the point when first released and the moment the block hits the spring. Write out the energy equation between the points when first m = 2.00 kg b. released and when the spring is at maximum compression. c. If t, is small enough, the block will rebound back up the incline 2 meters past the unstretched spring. Write out the energy equation between the points when first released and the moment the block 4.00 m rebounds to its maximum height. 8. A vertical spring, of force constant "k", has one end tied to the ground and the other end tied to a vertical string that passes over a pulley and connected to a block of mass "m". Initially the block is held so that the spring is unstretched, When the block is released the block drops causing the spring to stretch. Given [k, m] Determine a. The maximum stretching of the spring. b. The acceleration of the block when the spring is at maximum stretch. 53.1 9. The potential energy function of a particle as a function of distance x is given by U = Axs_Bx3, where A and B are positive constants. a. Find the expression for the force as a function of x. b. Determine the equilibrium points and are they stable or unstable? 8 a peg located a distance "d" below the point of suspension. The pendulum is released from rest fr position (0-90). Given [L] Determine the minimum value of d so that the pendulum swings in a 10. A pendulum of length "L" swings in a vertical plane. When the pendulum gets to its lowest p 2
