The coefficient of kinetic friction between the floor and the block is 0.410. The block and spring are released from rest and the block slides along the floor. What is the speed of the block when it has moved a distance of 0.0110 m from its initial position? (At this point the spring is compressed 0.0260 m.)a spring gun with a spring constant of 9800 N/m is compressed 10cm from its natural length and then shoots a ball of 1 kg vertically upward. what is the maximum height the ball can reach (in meter)?A 2.50 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0300 m.
