Question

Question 5.
An object of mass m and velocity v has kinetic
energy= 200J. Find the new kinetic energy if the
mass of the object becomes double and velocity
still remains the same?
PL​

Answer 1

Answer:

x = 1/2*m*v^2=200j

in second case

let the kinetic energy be x'

v'=v

m'=2m

x'= 1/2*2m*v^2

x'= 2(1/2*m*v^2)

x'=2(x)

x'=2*200j

x'=400j
