Question

A boy pulls a 6.5 kg sled along the snow with a force of 7.5 N angled at 30° above the horizontal. If the sled is accelerating at 0.15 m/s^2, what is the net force acting on the sled?

a) 7.5 N
b) 6.5 N
c) 5.0 N
d) 3.5 N

Answer 1

To find the net force on a sled, you multiply its mass by the acceleration. In this scenario, the provided data suggests a net force of 0.975 N, which does not match any of the given options. This indicates there might be an error in the question.

Step-by-step explanation:

The net force acting on an object is given by Newton's second law of motion, which states that the net force (F_net) is equal to the mass (m) of the object multiplied by its acceleration (a). In this case, the student is asked to calculate the net force acting on a sled. The formula is: F_net = m * a.

Given the mass of the sled is 6.5 kg and the acceleration is 0.15 m/s², we can calculate the net force as follows:

F_net = 6.5 kg * 0.15 m/s² = 0.975 N

However, this result does not match any of the provided options, suggesting a misunderstanding in the question or options given. Normally, the calculation would be straightforward, but it appears there may be an error in the question or the options provided.
