Answer:
If you need the explanation, just ask.
Answer:
None of these (see below).
Step-by-step explanation:
y = m cos pt - n sin pt
Using the chain rule:
dy/dt = m * -sin pt * p - ( n * cos pt * p)
= -mp sin pt - np cos pt.
dy/dt^2 = -mp * -cos pt * p - (np * - sin pt * p)
= mp^2 cos pt + np^2 in pt.
12.
3/4 of a foot = 9”
9 feet = 108”
108/9= 12, which is your final answer
Dy/dx h = 32t - 16t^2
v = 32 - 32t
at Max hight speed is 0m/s
therefore
0 = 32 - 32t
t = 32/32 = 1 s
so it goes up to Max hieght in 1 s
and it takes another 1s to come back
thus time after launch to return to ground is 2s!
