Answer 1

~150 J

thats what i came up with...this question is quite simple

Answer 2

18 lbs

Explanation:

We are given that a wagon filled with groceries weighing 36 pounds begins to roll down a hill having an incline
`30^(\circ)`.

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

`\theta=30^(\circ)`

Then, the force is required=
`mg sin\theta`

Substitute the values then we get

`F=36 sin 30^(\circ)`

F=18 lbs

Hence, the force required to keep the wagon from sliding down the hill=18 lbs
