Question

Find the x-component of vector d?  = (110m , 15? below +x-axis).

I already got this question wrong and the answer given was 106m. I tried calculating it every way I knew how and never came up with that number. Please explain to me in detail how they got this number. Concepts and math would be appreciated. The rest of the questions go as follows:

1. Find the y-component of vector d?  = (110m , 15? below +x-axis).
2. Find the x-component of vector v?  = (370m/s , 65? above +x-axis).
3. Find the y-component of vector v?  = (370m/s , 65? above +x-axis).
4. Find the x-component of vector a?  = (3.0m/s2 , ?y-direction).
5. Find the y-component of vector a?  = (3.0m/s2 , ?y-direction).

Explanation / Answer

x componenet of vector d=110sin15 (towards +ve x axis)

part 1)

y componenet of vector d=110cos15 (towards -ve y axis)

part 2)

x componenet=360sin65 (+ve x axis)

part 3)

y componenet=360cos65 (+ y axis)

part 4)

x component of vector a= 0 because vector is towards -y axis

part 5)

y componenet of vector a=3 (-ve y axis)
