The block compresses the spring a maximum distance of 6.50 cm from its rest position. The coefficient of kinetic friction between the block and the horizontal surface is o.490 What is the work done by the spring in bringing the block to rest? -6.04x101 3 iCorrecto! Su recilbo es 157-2342 Intentos Anteriores How much mechanical energy is being dissipated by the force of friction while the block is being brought to rest by the spring? 1.53 3 iCorrectol Su recibo es 157-4680 Intentos Anteriores What is the speed of the block when it hits the spring? 0.49m/s Use AK+AU again.

Explanation / Answer

Using conservation of energy

Kinetic energy on block= potential energy stored by the spring + frictional loss

0.5mv^2= 0.604 + 1.53

v= 0.933 m/s

Comment in case any doubt.. good luck
