Question
An airplane is traveling 835 km/h in a direction 41.5 west of north .(so 131.5 degrees i think)
Find the components of the velocity vector in the northerly and westerly directions.
Enter your answers using three significant figures separated by a comma. Already did, it was vnorth, vwest =
625,553 km/h
This is the part I need help with
Part B
How far north and how far west has the plane traveled after 2.10 h ?
Enter your answers using three significant figures separated by a comma. dnorth, dwest =
Explanation / Answer
a)
here
Northerly component,
835cos41.5 = 625.4 Km/h
westerly component,
835sin41.5 = 553.3 Km/h
b)
distance = speed * time
northerly distance = 625.4 * 2.10 = 1313.34 km
westerly distacne = 553.3 * 2.10 = 1161.93 km
