Can you please provide working out for this question

Starting from rest , a 1.90 kg box slides down a frictionless ramp, as shown below. The top of the ramp is 1.50m above the ground; the bottom of the ramp is 0.250m above the ground. The box leaves the ramp moving horizontally, and lands a horizontal distance d away a) Calculate the distance d b) Suppose the ramp in the question above is not 'ictionless. Find distance d the for the case in which 'iction on the ramp does -9.70 J of work on the box before it becomes airborne. 1.5 m
