Question
A toy car, 40 grams, is propelled by a constant force of 2.0 N. What is the acceleration of the toy car
Solution
To find the acceleration of the toy car, we can use Newton's second law of motion, which states that the acceleration of an object is equal to the net force acting on it divided by its mass. The formula is:
a = F/m
where: a is the acceleration, F is the force, and m is the mass.
Given: F = 2.0 N (Newtons) and m = 40 g (grams), but we need to convert this to kilograms because the standard unit of mass in this formula is kilogram. 1 gram is equal to 0.001 kilogram, so m = 40 * 0.001 = 0.04 kg.
Now we can substitute the values into the formula:
a = F/m a = 2.0 N / 0.04 kg a = 50 m/s²
So, the acceleration of the toy car is 50 meters per second squared.
