what is the force used to accelerate a 50g toy car at a rate of 4m/s/s?
To determine the force used to accelerate a toy car, you need to use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
In this case, the mass of the toy car is given as 50 grams. However, it is often easier to work with mass in kilograms, so we need to convert grams to kilograms. Since 1 kilogram (kg) is equal to 1000 grams (g), the mass of the toy car is 50 grams / 1000 = 0.05 kg.
The acceleration of the toy car is given as 4 m/s².
Using Newton's second law of motion, we can calculate the force as follows:
Force (F) = mass (m) x acceleration (a)
F = 0.05 kg x 4 m/s²
F = 0.2 Newtons (N)
Therefore, the force used to accelerate the 50g toy car at a rate of 4 m/s/s is 0.2 N.
