Answer:
18 lbs
Step-by-step explanation:
We are given that a wagon filled with groceries weighing 36 pounds begins to roll down a hill having an incline [tex]30^{\circ}[/tex].
We have to find the value of force required to keep the wagon from sliding down the hill
Weight of wagon filled with groceries=36 pounds
[tex]\theta=30^{\circ}[/tex]
Then, the force is required=[tex]mg sin\theta[/tex]
Substitute the values then we get
[tex]F=36 sin 30^{\circ}[/tex]
F=18 lbs
Hence, the force required to keep the wagon from sliding down the hill=18 lbs
