Question

A sled of mass 200 kg is being pulled by 4 dogs across the

snow (μ kinetic = .15). a) If each dog can pull with a force of 85
N, determine the acceleration of the sled.

Answer 1

The acceleration of the sled is 1.7 m/s^2 when each dog exerts a force of 85 N.

Step-by-step explanation:

To determine the acceleration of the sled, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Given that each dog can pull with a force of 85 N and the mass of the sled is 200 kg, the net force acting on the sled can be calculated as:

Net Force = Sum of the forces (85 N * 4 dogs) = 340 N

The acceleration of the sled can be calculated as:

Acceleration = Net Force / Mass = 340 N / 200 kg = 1.7 m/s^2
