please answer this question. thank you

Answer 1

given

mass m = 0.150 kg

height h = 0.850 m

acceleration due to gravity g = 9.80 m / s²

(a)

work done = m g h

= (0.150) (9.8) (0.850)

= 1.2495 J

(b)

the work done is equal to potential energy

(c)

1 cal = 4.186 J

nergy spent once = 1.2495 J

= 0.298 cal

= 0.3 cal

for 35 tims

food calories = (0.3) (35) = 10.5 cal
