Question

1000 kg car moves in speed of 15m/s How much kinetic energy does it have?

Answer 1

Explanation:

Given mass of the car(m)=1000kg

speed of the car(v)=15m/s

Kinetic energy=1/2mv^2

=1/2×1000×15×15

=112500J

Answer 2

Answer:

112500 J

Explanation:

Use formula

KE =1/2 mv^2

given mass = 1000 kg ; v=15 m/s

therefore,

KE= 1/2* 1000* 15* 15

= 112500 joules

Hope it helps.
