Question

A boy pulls a 6.5 kg sled along the snow with a force of 7.5 n angled at 30 degrees above the horizontal. the sled is accelerating at 0.15 m/s^2?

a. 4.78 N
b. 7.5 N
c. 8.66 N
d. 10.35 N

Answer 1

The force pulling the sled is 0.975 N, which is closest to option A, 4.78 N.

Step-by-step explanation:

To find the force pulling the sled, we can use Newton's second law of motion, which states that force (F) equals mass (m) times acceleration (a). In this case, the mass of the sled is 6.5 kg and the acceleration is 0.15 m/s^2. So, the force can be calculated as:

F = m * a
F = 6.5 kg * 0.15 m/s^2
F = 0.975 N

Therefore, the force pulling the sled is 0.975 N. The closest option to this value is option A, 4.78 N.
