Answer:
1768.25 N
Step-by-step explanation:
We are given that
Weigh of car=w=2750 pounds
[tex]\theta=40^{\circ}[/tex]
We have to find the force required to keep it from rolling down the hill.
Force required to keep it from rolling down the hill=[tex]wsin\theta[/tex]
Substitute the values
Force required to keep it from rolling down the hill=[tex]2750sin40[/tex]
Force required to keep it from rolling down the hill=[tex]2750\times0.643[/tex]
Force required to keep it from rolling down the hill=1768.25 N
