Answer:
I believe the answer is 1659
Step-by-step explanation:
395 ÷ 20 = 19.75
19.75 × 84 = 1659
3/4 = 0.75
10.5 / 0.75 = 14 samples can be made.
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
The interior angles sum to 180°, so the missing angle has measure
180° - 106° - 12° = 62°
Use the law of sines to find RS:
sin(106°)/RS = sin(62°)/34 ⇒ RS = 34 sin(106°)/sin(62°) ≈ 37
