Question

a 1150 kg car is on a 8.7 degree hill. Using X-Y axes tilted down the plane what is the y component of the weight

Answer 1

11140.326 Newtons

Explanation

Step 1

diagram and F.B.D

F.B.D

Step 2

now, we neend to solve for the adjancet side of the right triangle formed by the weight magnitude, its y-component and the x-component

therefore

$\begin{gathered} y-component\text{ =}-1150kg*9.8\frac{m}{s^2}*cos8.7 \\ y-component\text{ =11140.326 Newtons} \end{gathered}$

so, the answer is 11140.326 Newtons

I Hope this helps you
