# The Collar Has A Mass Of 20kg The collar has a mass of 20 kg and slides along the smooth rod. TWo springs are attached to it and the ends of the rod as shown. If each spring has an uncompressed length of 1 m and the collar has a speed of 2 m/s when s = 0, determine the maximum compression of each spring due to the back-and-forth (oscillating) motion of the collar. Two children sit on a seesaw. One has a mass of 20 kg and sits 1.0 m from the pivot point. If the other children has a mass of 23 kg, how far must she sit from the pivot to balance the seesaw? Question: The block has a mass of 20 kg and is released from rest when s=0.5 m. If the mass of the bumpers A and B can be neglected, determine the maximum deformation of each spring due to collision. The crate, which has a mass of 100 kg, is subjected to the action of the two forces. If it is originally at rest, determine the distance it slides in order to attain a speed of The coefficient of kinetic friction between the crate and the surface is m k = 0.2. The 4-kg smooth collar has a speed of 3 ms when it is at s = 0. Determine the maximum distance s it travels before it stops momentarily. The spring has an unstretched length of 1 m.

Problem 14-84

The 4-kg smooth collar has a speed of 3 m>s when it is at s = 0. Determine the maximum distance s it travels before it stops momentarily. The spring has an unstretched length of 1 m.
