Answer:
F = 2700 N
Explanation:
Given that,
Mass of a car, m = 3000 kg
Initial velocity, u = 15 m/s
Final velocity, v = 60 m/s
Time, t = 5 s
We need to find the net force on the car during this time . The net force on an object is given by the product of mass and acceleration. So,
F = ma
a is acceleration, a = (v-u)/t
[tex]F=\dfrac{m(v-u)}{t}\\\\F=\dfrac{3000\times (60-15)}{5}\\\\F=27000\ N[/tex]
So, 27000 N is the net force on the car during this time .
