Find x-component of vector d=(110m , 46 degrees below + x-axis).

Question

Find y-component of vector d=(110m ,46 degrees below + x-axis).
Find x-component of vector v=(350m/s , 28degrees above + x-axis).
Find y-component of vector v=(350 , 28 above + x-axis).
Find x-component of vector a=(9.0 , - y-direction).
Find y-component of vector a=(9.0 , - y-direction).

Answer 1

d(x)=dcos46⁰=110•cos46⁰=76.4 m.
d(y) =- dsin46⁰=- 110•sin46⁰= - 79.1 m.
v(x) = vcos28⁰=350•cos28⁰= 309 m/s
v(y) = vsin28⁰=350•sin28⁰=164.3 m/s
a(x) = 0
a(y) = - 9 m/s²
