4. A block of 3 kg mass is released from rest at a height of 5 m on a curved smooth slope. At the foot of the ramp there is a spring with a constant k = 400 N/m. The block moves down a ramp towards the spring, when it hits the end of the spring the block gets a frictional force with the floor (µ=0.2) and compresses the spring a distance x before being stationary for a moment. Define: a) the speed of the block when it hits the end of the spring %3D b) length x (maximum compression the block can exert) A 5 m
