Answer:
See below
Step-by-step explanation:
Y component of velocity is 70 sin 30°
y position = 3 + 70 sin 30° * t - 1/2 a t^2
when the ball hits the ground y = 0
0 = 3 + 70 sin 30° t - 1/2 (32.2)t^2
- 16.1 t^2 + 35t + 3 = 0
Use Quadratic Formula to find t = <u>2.26 seconds</u>
Horizontal component of initial velocity
70 cos 30° distance horizontal = 70 cos 30° * t
= 70 cos 30° (2.26) =<u> 137.0 ft</u>
Answer:
p = -2
Step-by-step explanation:
15 = -4p + 7
4p + 15 = 7
4p + 15 - 15 = 7 - 15
4p = -8
4p/4 = -8/4
p = -2
If we use the surface of the water as our frame of reference, then Christy's vertical position could be represented by -12 ft.
(a)7x4=28
