A block of mass m=1.40kg slides along a horizontal table with speed Vo=2.50m/s. At x=0 it hits a spring with spring constant k=40.00N/m and it also begins to experience a friction force. The coefficient of friction is give by mew=0.100. How far did the spring compress when the block first momentarily come to rest.
