Question

if a engine supplies 100 joules of energy to a weight of 200g . How high it can be lifted ?( given g = 8 metre per second square)?​

Answer 1

Explanation:

2/10*8*h=100

h=125/2

Answer 2

Energy supplied = 100 Joules

Weight of the object that had energy transferred =200 g

G = 10m²

$\large\underline{\boxed{\blue{To,Find}}}$

High can be lifted

$\large\underline{\boxed{\blue{Solution}}}$

Apply work energy theorem

Work done = M × G × H

$\implies$ 100 = 200× 10 × H

$\implies$ 100 = 2000 × H

$\implies$ 100/2000 = H

$\implies$ 0.5m = H

Hence, H = 50cm.
