Question

if an engine supplies 100j of energy to weight of 200g. how high it can be lifted ? (given = 9.8m/s2

Answer 1

Answer:

51.020 m

Explanation:

enery supplied = 100 j.

weight to be lifted =0.2 kg

acceleration due to gravity= 9.8m/s^2

work done = potential energy = mgh

100=0.2*9.8*h

h=51.020m
