Question

You pull a sled with a package on it across the snow-covered flat lawn. If you apply a force of 46.8 N to the sled and it accelerates at 0.75 m/s^2, what is the combined mass of the package and the sled? Assume there is no friction.

Answer 1

To find the combined mass of the package and the sled, use Newton's second law of motion: F = ma. Rearrange the equation to solve for mass and substitute the given values to find the answer.

Step-by-step explanation:

To find the combined mass of the package and the sled, we can use Newton's second law of motion. The formula for Newton's second law is:

F = m x a

Where F is the force applied, m is the mass, and a is the acceleration.

In this case, the force applied is 46.8 N and the acceleration is 0.75 m/s^2. Rearranging the equation to solve for mass, we have:

m = F / a

Substituting the given values, we get:

m = 46.8 N / 0.75 m/s^2 = 62.4 kg

Therefore, the combined mass of the package and the sled is 62.4 kg.
