Question

What is effect in kinetis energy and momentum when mass of a body in a projectile motion is halved?

Answer 1

Kinetic energy and momentum are also halved

Explanation:

Both kinetic energy and momentum are directly proportional to mass.

`KE = 1/2 * m * v^2`

`p = m*v " "(p " is momentum")`

I hope this helps,
