Question

How much mechanical energy is being dissipated by the force of friction while the block is being brought to rest by the spring?
3.0710-1 J

What is the speed of the block when it hits the spring?

Consider ?K+?U=?E. What quantities in the problem correspond to each of the variables in the equation? A moving 2.50 kg block collides with a horizontal spring whose spring constant is 272 N/m. Previous Tries What is the speed of the block when it hits the spring? The block compresses the spring a maximum distance of 2.50 cm from its rest position. The coefficient of kinetic friction between the block and the horizontal surface is 0.500. What is the work done by the spring in bringing the block to rest? Consider ?K+?U=?E. What quantities in the problem correspond to each of the variables in the equation? Submission not graded. Use more digits. Tries 2/8 Previous Tries How much mechanical energy is being dissipated by the force of friction while the block is being brought to rest by the spring? 3.07½10-1 J You are correct. Your receipt no. is 157-2152

Explanation / Answer
