Question

question 23 (problem reference 4 - 2) a boy pulls a 5.00 - kg sled with a rope that makes a 60.0° angle with respect to the horizontal surface of a frozen pond. the boy pulls on the rope with a force of 10.0 n; and the sled moves with constant velocity. what is the weight of the sled? a. 49.0 n b. 5.00 n c. 10.0 n d. 98.0 n

Explanation:

Step1: Recall weight formula

The weight formula is $W = mg$, where $m$ is the mass and $g$ is the acceleration due to gravity ($g= 9.8\ m/s^{2}$).

Step2: Identify mass value

The mass of the sled $m = 5.00\ kg$.

Step3: Calculate weight

$W=mg=5.00\ kg\times9.8\ m/s^{2}=49.0\ N$

Answer:

A. 49.0 N
