Physics

To determine the force exerted by Y on X and their accelerations we can follow these steps:

Step 1: Determine the force exerted by Y on X

According to Newton's Third Law, the force that sled X exerts on sled Y is equal in magnitude and opposite in direction to the force that sled Y exerts on sled X. Therefore, if X exerts a force of 30 N on Y, then Y exerts a force of 30 N on X.

Step 2: Determine the accelerations of X and Y

For Sled X:

Using Newton's Second Law:

Where:

(force exerted by X on Y, and also the force exerted by Y on X),

(mass of sled X).

Calculating the acceleration of X:
