Question

has
A moving body of mass 0,3 kg
60J of Kinetic energy. Calculate the
speed of the body?​

Answer 1

Answer:

please follow me

Explanation:

sorry

Answer 2

Given, m = 0.3 kg

KE = 60J

v = ?

Now, KE = 1/2 mv²

or, 60 = 1/2 ×0.3×v²

or, 60 = 0.5×0.3 v²

or, 60 = 0.15 v²

or, 0.15 v² = 60

or, v² = 60/0.15

or, v² = 400

or, v = √400

= √(20)²

= 20 m/s.

Thus, speed of the body is 20 m/s.

I hope this helps.
