An object of mass 300 kg is observed to accelerate at the rate of 4 m/s 2 . Calculate the force required to produce this acceleration.

To calculate the force required to produce this acceleration, we can use Newton's second law of motion, which states that the force applied to an object is equal to the mass of the object multiplied by its acceleration.

So, the force required (F) can be calculated using the formula:
F = m * a

where
F is the force,
m is the mass, and
a is the acceleration.

Given that the mass (m) is 300 kg and the acceleration (a) is 4 m/s^2, we can substitute these values into the formula:

F = 300 kg * 4 m/s^2

F = 1200 kg*m/s^2

Therefore, the force required to produce the given acceleration is 1200 Newtons (N).
