horizontal speed: 215 cos18º
vertical: 215 sin18º
too bad you didn't show how you got your "weird' results...
Upon reaching a speed of 215 km/h on the runway, a jet raises its nose to an
angle of 18º with the horizontal and begins to lift off the ground.
a. Calculate the horizontal and vertical components of its velocity
at this moment.
b. What is the physical interpretation of each of these components
of the jet’s velocity?
*how do I draw this properly? I drew a triangle and ended up with an angle of 162 across from the resultant. I solved for the other sides and got weird numbers. The textbook answer is a) 204km/h, 66km/h
