Question

A car of mass 1500 kg is moving with the speed of 72 km/ hr (calculated it's kinetic energy)​

Answer 1

So work require will be 3888×10×10³J

Step-by-step explanation:

⇒Work done=Change in kinetic energy

⇒KE=1/2mv²

⇒Mass->15000kg

⇒Velocity->72km/h

⇒KE=1/2×15000×(72)²

⇒KE=1/2×15000×5184

⇒KE=7500×5184

⇒KE=3888×10×10³J
