Can these please be solved on paper with a step by step explanation and a body diagram when necessary 4)11.3 m/s5)875 J6)1.36m

4) A block is at the base of a ramp of angle 35. The ramp is 5 m long and has coefficients of static and kinetic friction of 0.6 and 0.2, respectively. If the block is initially given a velocity of 12 m/'s up the ramp, what will be its velocity right before it hits the ground? "5) An 80 N box is pushed up a 30 ramp by a 100 N force that is applied parallel to the ramp surface. The ramp has coefficients of static and kinetic friction of 0.8 and 0.22, respectively. The box is moved 20 m up the ramp. Calculate the change in kinetic energy of the box while it is moved up the ramp. 6) A block of mass 1.5 kg compresses a movable spring platform 10 cm from equilibrium. The spring has a constant of 2000 N/m. The ramp has no friction. If the block is released from rest, calculate the distance from its starting point that the block travels up the ramp.
