How can i help you please guide me?
So you know the horizontal acceleration is zero
integrating this you can find the horizontal velocity as
<span><span>vh</span>=Vcos(α)</span>
V = initial velocity 1200 ft/sec
the angle is 45 so you have
<span><span>vh</span>=1200cos(45)</span>
if you integrate this equation with respect to time (t) you get the horizontal displacement equation.
the initial condtions for the horizontal displacement seem to bet at t = 0, x = 0
then when you get the equation, just substitute t = 2 and evaluate
Answer:
x = 56°
Step-by-step explanation:
DAF is a straight line so it has a measurement of 180°
180° - 64° - 60° = x
x = 56°
