Question

a toy rocket is launched at an angle of 55 degrees above horizontal with an initial velocity of 150 m/s. what is its initial horizontal velocity and initial vertical velocity. use 1 cm = 10 m/s

Answer 1

i think you are supposed to use the graph for this :P.. but you can use trig as well!!

Answer 2

horizontal velocity =150cos(55)
vertical velocity=150sin(55)

Answer 3

horizontal V cos55 and vertical V sine55
