What is the error in calculating the y-component of the force created by a hanging mass (m=432.23g) at an angle of 28º? Take g=9.81m/s^2)Homework Equations
Fg = mg
The Attempt at a Solution
Fg = mg
= (0.43223kg +/- 0.000005kg)(9.81m/s +/- 0.05m/s)
= (0.43223 +/-...

Hi, I am having troubles with a question concerning relative motion. The problem goes:
A plane is traveling at an air speed of 285 km/h [E45ºS]. A wind is blowing to the northeast at 75 km/h [N22ºE] relative to the ground. Determine the velocity relative to the ground.
