Question

an object moving at a speed of 10 metre per second possesses the kinetic energy of 25 Joulefind the mass of the object​

Answer 1

Answer:

k.e = 1/2 mv2

here v=10m/s , k.e = 25 j

25 = 1/2 × m × 10× 10

100m = 50

m = 1/2 kg

Answer 2

Answer: 0.5

Explanation:

We know the formula of kinetic energy is

E. K. = 1/2* mv^2
