. Anne is pushing a wheelbarrow filled with mulch to place in her garden. She is pushing the wheelbarrow with a force of 70 N at

Kruka [31]

<u>Answer:</u>

When Anne pushes the wheelbarrow 25 meters the work done is 1120 joules

<u>Solution:</u>

We know $\text { Work }(\mathrm{W})=\text { Force }(\mathrm{F})\times\text { Distance (D) }$

Anne is pushing the wheelbarrow with a force of 70 N at an angle of $50^{\circ}$ with the horizontal

So the force of Anne will be $F=70 \cos 50^{\circ}=(70 \times 0.64)=44.8 \mathrm{N}$

She pushes the wheelbarrow 25 meter, So D = 25 meters

So, the $work,F\times D=(44.8 \times 25)=1120 \text { Joules }$

Anne has done total 1120 joules work.

A triangle has the following measurements: B=79 degrees a=5ft

11Alexandr11 [23.1K]

The law of cosines for this particular situation is b^2 = a^2 + c^2 - 2ac cosB.
Filling in what you know, you have b^2 = 25 + 49 - [2(5)(7)-.1908], which simplifies to b^2 = 74 - 69.8092 which gives you a b^2 value of 4.1908, but you have to take the square root of that so you get a side value for b of 2.05.
