Question

You pull a sled with a package on it across a snow-covered flat lawn. If you
apply a force of 46.8 N to the sled, it accelerates at 0.75 m/s2. What is the
combined mass of the package and the sled? (Assume there is no friction.)
A. 62.40 kg
B. 52.50 kg
C. 96.75 kg
D. 35.10 kg

Answer 1

Answer:

m = 62.4 kg

Explanation:

The force applied to the sled, F = 46.8 N

Acceleration of the sled, a = 0.75 m/s²

We need to find the combined mass of the package and the sled. Let it is m. Using definition of force as follows :

F = ma

$m=\dfrac{F}{a}\\\\m=\dfrac{46.8}{0.75}\\\\m=62.4\ kg$

So, the mass of the package and the sled is 62.4 kg.
