A 1420-kg car is traveling with a speed of 12.4 m/s. What is the magnitude of the horizontal net force that is required to bring
zzz [600]

Answer:

1419.01436 N

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{0^2-12.4^2}{2\times 78}\\\Rightarrow a=-0.98564\ m/s^2

The force on the car

F=ma\\\Rightarrow F=1420\times -0.98564\\\Rightarrow F=-1419.01436\ N

Magnitude of the horizontal net force that is required to bring the car to a halt is 1419.01436 N
