Question

A body a sense a slope with a speed of 10 M per second if 105 joules of energy is lost due to friction the height to which the body will rise is Gravity 10 metre per second square

Answer 1

Answer:

0.2m

Explanation:

Given,

v = 10m/s , E = 105J and g = 10m/s²

use, E = mgh = mv²/2

gh = v²/2

h = v²/2g

putting value

h = (2)²/(2x10) = 4/20 = 1/5 m = 0.2m
