Answer: The net force acting on the car 1,299.3 N.
Explanation:
Mass of the car = 710 kg
Initial velocity of the car of the ,u= 37 km/h= 10.27 m/s [tex](1km\h=\frac{5}{18} m/s)[/tex]
Final velocity of the car,v = 120 km/h = 33.33 m/s
time taken b y car = 12.6 sec
v-u=at
[tex]33.33m/s-10.27m/s=23.06 m/s=a(12.6 sec)[/tex]
[tex]a = 1.83 m/s^2[/tex]
[tex]Force=mass\times acceleration[/tex]
[tex]Force=710 kg\times 1.83 m/s^2[/tex]
[tex]Force=1,299.3 N[/tex]
The net force acting on the car 1,299.3 N.
