Question

A 1400-kg car is moving at a speed of 25 m/s. How much kinetic energy does the car have?

Answer 1

437,500 Joules

Step-by-step explanation:

KE= 1/2 × M

x V^2, where

M = Mass,

V = Velocity

KE = 1/2 × 1400 × 25^ 2

KE= 1/2 × 1400 × 625

KE = 437,500 Joules.

Answer 2

Kinetic energy=1/2mvsquare

1/2 x 1400 x 25 x25

Therefore kinetic energy= 437500Joules
