(a) calculate the number of kilocalories needed to climb 232 stair steps (116 steps per minute for 2 min.)

*climbing stairs (116/min.) = energy consumption rate is 9.8 (kcal/min) *

(b) calculate the gain in gravitational potential energy for a 50-kg person if each step 0.18m high and compare your result with the answer to part (a). explain why the energy found in part (a) is larger than that found in part (b)

come on guys, help please? i need this asap :(

thank you so much !
