Question: You pull a short refrigerator with a constant force F across a greased (frictionless) floor, either with F horizontal (case 1) or with F tilted

You pull a short refrigerator with a constant force F across a greased (frictionless) floor, either with F horizontal (case 1) or with F tilted upward at an angle θ (case 2).

(a) What is the ratio of the refrigerator's speed in case 2 to its speed in case 1 if you pull for a certain time t?

(b) What is this ratio if you pull for a certain distance d?
