Question

a body of mass 60 kg is moving with the speed of 500 m/s . find its Kinetic energy​

Answer 1

Solution :-

Given ,

• Mass of body = 60kg
• Speed of body = 500 m/s

Note :- Make sure that all the units should be in S.I. units .

As we know that ,

◉ K.E. = 1/2 mv²

=> K.E. = 1/2 × 60 × 500

=> K.E. = 30 × 500

=> Kinetic energy = 15000J

Hence , K.E. = 15000J

Formulae

• F = m × a
• a = ∆v/t
• s = ut + 1/2 at²
• v = u + at
• v² - u² = 2as
• P = F/A
