Final answer:
The force required to make a 2 kg toy car accelerate at 5 m/s² is calculated using Newton's second law of motion, F = m × a, which results in a force of 10 N.
Step-by-step explanation:
To find the force that should be applied to a toy car with a mass of 2 kg to make it accelerate at 5 m/s2, we can use Newton's second law of motion, which states that the force (F) acting on an object is equal to the mass (m) of the object multiplied by the acceleration (a) of the object. The formula is F = m × a.
In this case, the mass of the car is 2 kg and the acceleration is 5 m/s2. So, we calculate the force as follows:
F = m × a
F = 2 kg × 5 m/s2
F = 10 N
The correct answer would then be a. F=10N, as this is the force required to make the toy car accelerate at 5 m/s2.
