Question

Draw each of the following vectors on graph paper, then find the x- and y- components. Make sure to include units in your answers for the components.
a) ⃑r = (65 m, 30degrees above the positive x-axis)
b) ⃑v = (125 m/s, 40degrees below the negative x-axis)
c) ⃑a = (5.3 m/s2, 15degrees to the right of the positive y-axis)

Answer 1

a) Vx = 65 cos 30, Vy = 65 sin 30

b) Vx =125 cos 40, Vy = -125 sin 40

c) Vx = 5.3 sin 30 , Vy = 5.3 cos 30

of course sin 30 = 1/2 and cos 30 = sqrt3/2
