The 10-kg block shown in the figure below rests on the smooth incline. If the spring is originally stretched 0.5 m, determine the velocity of the block when a horizontal force P = 400 N pushes it up the plane s = 2 m
Q4: The slider block B is confined to move within the smooth slot. It is connected to two springs, each of which has a stiffness of k = 30 N/m. They are originally stretched 0.5 m when s 0 as shown. Determine the maximum distance, smax, block B moves after it is hit by block A which is originally traveling at (vA) = 8 m/s. Take e = 0.4 and the mass of each block to be 1.5 kg. Ans.: Smax. = 1.53 m 2 m k- 30 N/m (va) =8 m/s 2 m k - 30 N/m
1. Block A has a mass of 0.5 kg and slides on a frictionless shaft. The spring of k = 10 N/m had an unstretched length of 0.17 m before being stretched to attach to block A. If the block is released from rest, determine how fast the block is traveling right before it hits the ground. The distance d = 1.0 m. 0.8m wak = 10% 4-
The 12-lb box slides on the surface for which pux=0.3. The box has a velocity u = 15 ft/ s when it is 2 ft from the plate. (Figure 1) If the box strikes the smooth plate, which has a weight of 25 lb and is held in position by an unstretched spring of stiffness & = 360 lb / ft, determine the maximum compression imparted to the spring. Take e = 0.8 between the box and the plate. Assume that the plate slides smoothly. Express your answer using three significant figures and include the appropriate units. x=? v = 15 ft /s k 2 ft
