What is the acceleration of a car moving at a force of 400 N and a mass of 800 kg?
To calculate the acceleration of a car, you need to use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. The formula for this relationship is:
acceleration (a) = net force (F) / mass (m)
In this case, the net force acting on the car is 400 N, and the mass of the car is 800 kg. Plugging these values into the formula, we can calculate the acceleration:
a = F / m
a = 400 N / 800 kg
a = 0.5 m/s²
Therefore, the acceleration of the car is 0.5 m/s².
