Question:

You know you can provide $500 \mathrm{~W}$ of power to move large objects. You need to move a $50-\mathrm{kg}$ safe up to a storage loft, $10 \mathrm{~m}$ above the floor.

(a) With what average speed can you pull the safe straight up?

(b) How much work do you do on the safe in doing this?

(c) With what average speed can you pull the safe up a $30^{\circ}$ incline?

(d) How much work do you do on the safe moving if you slide it up the incline to the loft?
