A sled of mass 50 kg is pulled along a snow-covered, flat surface with a force of 200 N. the friction force acting on the sled is 49 N. what is the acceleration?
To find the acceleration of the sled, we can apply Newton's second law of motion, which states that the net force acting on an object is equal to the product of its mass and acceleration.
Given:
Mass of the sled, m = 50 kg
Force applied, F = 200 N
Friction force, Ff = 49 N
Net force, Fn = F - Ff
Now, we can use the equation F = m * a, where F is the net force and a is the acceleration.
So, substituting the values into the equation, we have:
Fn = m * a
200 N - 49 N = 50 kg * a
151 N = 50 kg * a
To find the acceleration, we rearrange the equation:
a = Fn / m
a = 151 N / 50 kg
a ≈ 3.02 m/s²
Therefore, the acceleration of the sled is approximately 3.02 m/s².
