Question

A car mass is 141 kg that is moving at 4m/s what is the kinetic energy of a car​

Answer 1

Given:-

A car mass is 141 kg that is moving at 4m/s. What is the kinetic energy of a car?

Solution:-

Mass of the car= 141 kg (m)

Velocity of the car = 4m/s (v)

Therefore,

Kinetic energy=

=(1/2)mv^2

=(1/2)(141)(4)^2

=(1/2)(141)(16)

=(141)(8)

=1128 joules
