Question 2
The spring has a stiffness k and an unstretched length 1o. As shown, it is confined by the
plate and wall using cables so that its length is 1. A block of weight Wis given a speed va
when it is at 4, and it slides down the incline having a coefficient of kinetic friction . If
it strikes the plate and pushes it forward a distance l, before stopping, determine its speed
at A. Neglect the mass of the plate and spring.
Given:
W = 20 N
= 0.66 m
1 = 0.5 m
l = 0.08 m
d = 1 m
