KE = 1/2mv^2
KE = 200J
M = 1500kg
V = unknown
200J = 1/2(1500kg)v^2
200J = 750(v^2)
200/750 = v^2
v = squareroot(200/750)
v = 0.5164 m/s

The speed the car is going is 0.52m/s

How to calculate the kinetic energy of a body

Kinetic energy is the energy due to motion of a body. It is expressed as:

KE = 1/2mv^2

Given the following parameters

m is the mass = 1500kg

KE = 200Joules

Substitute

200 = 0.5(1500)v^2

200 = 750v^2

v^2 = 200/750

v = 0.52m/s

Hence the speed the car is going is 0.52m/s
