Two boxes are connected to each other as shown. the system is released from rest and the 1.00-kg box falls through a distance of 1.00 m. the surface of the table is frictionless. what is the kinetic energy of box b just before it reaches the floor?

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

Hence, The kinetic energy of box b is 2.44 J.
