question 16 of 20
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. 52.50 kg
b. 96.75 kg
c. 62.40 kg
d. 35.10 kg

Explanation:

Step1: Recall Newton's second law

$F = ma$

Step2: Rearrange for mass

$m=\frac{F}{a}$

Step3: Substitute values

$m=\frac{46.8\ N}{0.75\ m/s^{2}} = 62.4\ kg$

Answer:

C. 62.40 kg
