a) Determine the potential energy within the spring when the slider is at point A and determine the potential energy in the spring when the slider is at point B? b) Calculate the speed velocity b of the slider when it reaches point B. c) Assume now that the normal force exerted by the guide on the slider at point B is 84.1 N, find the radius of curvature ρB of the guide.
A slider with a mass of 0.6 kg is connected to a spring with a of stiffness k = 120 N/m and, as pictured below, slides down a smooth parabolic guide. This guide lies in a vertical plane and the slider is released from a stationary position. The length of the spring when unstretched is 0.2 m.
a) Determine the potential energy within the spring when the slider is at point A and determine the potential energy in the spring when the slider is at point B?
b) Calculate the speed velocity b of the slider when it reaches point B.
c) Assume now that the normal force exerted by the guide on the slider at point B is 84.1 N, find the radius of curvature ρB of the guide.
d) Determine the initial speed velocity a (at point A) (downward direction) that the slider would need to reach a speed at B equal to double to the from part b).
