energy? ​

Answer 1

see my attachment explains it all..

hope it helps :)

Answer 2

Answer:

KE = 160 Kilojoule

Explanation:

Given,

A motorbike of mass 200 kg is moving with a velocity of 40 m/s.

To find,

 Its kinetic energy ?

Calculation:

•    Kinetic energy is a sub-type of mechanical energy possessed by an object by the virtue of its motion.

•    Let  mass be m, velocity be v.

             i.e., KE = 1/2(m$v^{2}$)

⇒ KE = 1/2 ×(200)×$40^{2}$

⇒KE = 1/2 × 200 × 1600

⇒ KE = 160000 joule

⇒KE = 160 kilojoule

so, Kinetic energy of motorbike is 160 kJ
