You are going to carry a 5.0-kg object up to the third floor of a building. The stairs you are going to carry the object up are
different for each floor. Calculate the amount of work you do for each set of stairs.
(a) The first set of stairs is 10.0 long (diagonal distance along the stairs) and tilted at 30.0°.
(b) The second set of stairs is 10.0 long and 5.0 m high (the top of the stairs is 5.0 m higher than the bottom of the stairs
(c) The third set of stairs is 15.0-m long and tilted at 19.47°.
(d) Calculate the amount of work gravity does in each case.
