Question

Two toys car A and B of masses 100g and 200g are moving with the same speed on a smooth surface. which of the two has greater kinetic energy ?​

Answer 1

Answer:

B - 200g

Explanation:

Step-by-step explanation:

Kinetic energy = (1/2)m V²

m = mass

v = speed/Velocity

v is same for both

but m is more for Car B than Car A

so CAR B has greater kinetic energy

Mark me brainliest :)

Answer 2

Kinetic energy =

Since the speed of both the cars is same, hence the car with greater mass will possess more kinetic energy.

Car B has more mass than Car A, hence the kinetic energy of car. B is greater.
