Answer:
The kinetic energy of box b is 2.44 J.
Explanation:
Given that,
Mass of box a =3.00 kg
Mass of box b=1.00 kg
Distance = 1.00 m
We need to calculate the acceleration of the system
Using formula of acceleration
put the value into the formula
We need to calculate the velocity
Using equation of motion
Put the value into the formula
We need to calculate the kinetic energy of box b
Using formula of energy
Put the value into the formula
