If a 60 kg person on a 15 kg sled is pushed with a force of 300 N, what will be the person's acceleration?
To determine the person's acceleration, you need to use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
Given:
Mass of the person (m1) = 60 kg
Mass of the sled (m2) = 15 kg
Force exerted on the person and sled (F) = 300 N
Since the force exerted on the person and sled is the same, we can rewrite the equation as:
F = (m1 + m2) * a
Plugging in the given values:
300 N = (60 kg + 15 kg) * a
Simplifying the equation:
300 N = 75 kg * a
Isolating the acceleration:
a = 300 N / 75 kg
a = 4 m/s²
Therefore, the person's acceleration is 4 m/s².
