Question

If the speed of the ball is doubled without affecting its mass, then the kinetic energy is

Answer 1

Quadrupled

Step-by-step explanation:

Kinetic energy = 1/2×mv^2

m= mass

v= velocity of object

Since mass is not changed

Kinetic energy is directly proportional to v^2

When v is doubled. v^2 is increased fourfold

[( v×2) ×(v× 2)] = v^2 ×4

So Kinetic energy is increased fourfold
