Question
A 500kg car accelerates from 10 m/s to 30 m/s in 4 seconds.
What is the magnitude of the net force applied? Write the calculations along with the answer.
Solution
Sure, to find the net force applied on the car, we first need to find the acceleration of the car.
The formula for acceleration is:
a = (v_f - v_i) / t
where: v_f = final velocity = 30 m/s v_i = initial velocity = 10 m/s t = time = 4 seconds
Substituting the values, we get:
a = (30 m/s - 10 m/s) / 4 s = 20 m/s / 4 s = 5 m/s²
Now, we can find the net force using the formula:
F = m * a
where: m = mass = 500 kg a = acceleration = 5 m/s²
Substituting the values, we get:
F = 500 kg * 5 m/s² = 2500 N
So, the magnitude of the net force applied on the car is 2500 Newtons.
