A62 kg boy and a 37 kg girl use an elastic rope while engaged in a tug-of-war on a friction-less icy surface. if the acceleration of the girl toward the boy is 2.2 m/s², determine the magnitude of the acceleration of the boy toward the girl.
answer in units of m/s².

The magnitude of the acceleration of the boy toward the girl is

Explanation:

It is given that,

Mass of the boy,

Mass of the girl,

The acceleration of the girl toward the boy is,

To find,

The acceleration of the boy toward the girl.

Solution,

Let is the magnitude of the acceleration of the boy toward the girl. We know that force acting on one object to other are equal in magnitude but opposite in direction. So,

So, the magnitude of the acceleration of the boy toward the girl is

a.   mass number from atomic number
