1. Achild pulls on a 6.5 kg sled with a net force of 14.2 N.Determine the sled's rate of acceleration.

Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is expressed by the formula:<br /><br />**F = ma**<br /><br />Where:<br /><br />* **F** represents the net force (in Newtons)<br />* **m** represents the mass (in kilograms)<br />* **a** represents the acceleration (in meters per second squared)<br /><br />In this problem, we are given:<br /><br />* **F** = 14.2 N<br />* **m** = 6.5 kg<br /><br />We need to solve for **a**. Rearranging the formula, we get:<br /><br />**a = F/m**<br /><br />Substituting the given values:<br /><br />**a = 14.2 N / 6.5 kg**<br /><br />**a ≈ 2.18 m/s²**<br /><br />Therefore, the sled's rate of acceleration is approximately 2.18 meters per second squared.<br />
