Question

6 formula 1 point a sled is pulled to the right by a tension force equal to 22 newtons. the sled feels a friction force of 3 newtons to the left. the sleds acceleration is equal to 5 meters per second per second. calculate the sleds mass in kg. answer previous next

Explanation:

Step1: Find net force

Net force \( F_{net} = F_{tension} - F_{friction} = 22\,\text{N} - 3\,\text{N} = 19\,\text{N} \) (right direction, positive).

Step2: Apply Newton's second law

Newton's second law: \( F_{net} = ma \), so \( m = \frac{F_{net}}{a} \). Substitute \( F_{net} = 19\,\text{N} \), \( a = 5\,\text{m/s}^2 \): \( m = \frac{19}{5} = 3.8\,\text{kg} \).

Answer:

\( 3.8 \)
