Question

A 120 kg go-cart is traveling at 13 m/s. Find the truck’s kinetic energy.

Answer 1

10.14 kJ

Step-by-step explanation:

From fundamental equation of energy, kinetic energy, KE is given by
`KE=0.5mv^(2)` where m is the mass of the object and v is the velocity of the same object

Given information

Mass, m=120 kg

Velocity, v=13 m/s

Substituting the given values of mass and velocity into the equation we obtain

`KE=0.5*120*13^(2)=10140 J=10.14* 10^(3) J=10.14 kJ`
