wind speed?
A car leaves point A and drives at 80.0km/h [E] for 1.50h. It then heads north at 60.0 km/h for 1.00 h and finally [30o W of N] at 100.0 km/h for 0.50 h, arriving at point B.
a) Determine the displacement of point B from point A.
b) A plane flies directly from point A to point B, leaving 2.00h after the car has departed from point A. It arrives at point point at the B at the same time the car arrives. There is a wind blowing at 60.0 km/h due south for the entire trip. What is the airplane's airspeed?
c) What direction must the plane head in order to arrive at point B?
d) How long would the plane's trip be if there was no wind?
Other then SOH CAH TOA, I have no idea
Used vectors to solve for part a. No idea for the other parts because my teacher hasn't taught the class with wind speed, and this is due for Tuesday
