Question

A truck has a mass of 8000kg and a car has a mass of 1000kg are traveling at the same speed. Which one has the greater energy? Why?

Answer 1

Answer:

the truck has the more energy because it's mass is more than car but then also it's speed is as same as car

please make it brainliest answer

Answer 2

Answer:The truck has more energy

Explanation:In this case energy means kinetic energy which is the energy of a body by virtue of its motion.

K.E=½mv²

Since velocity of both the vehicles is the same let's take velocity as v

K.E of car=½(1000)(v²)=500v² Joules

K.E of truck=½(8000)(v²)= 4000v² Joules

Thus the truck has more energy than the car
