1 pound equals 16 ounces
10 times 16 equals 160 ounces plus 1/2 a pound which is 8
168 ounces
The derivative of height with respect to time is
h'(t) = -32t +v
This will be zero when
0 = -32t +v
t = v/32
The height at this time is
h(v/32) = -16(v/32)² + v(v/32) = (v²)(-1/(2·32) +1/32) = v²/64
Setting this to 400, we get
400 = v²/64
v = √(64·400) = 160
The initial velocity required so that the maximum height is exactly 400 feet is
160 ft/s.
A. (0.5 meter) *
b. (0.5 meter) *
= (0.5 meter) *
= 0.1352 meter
This assumes you mean "The top of the first path is the initial height of 0.5 meter" which would then use n=3 as the top of the third path.
Answer:
10t
Step-by-step explanation:
The 1st thing we can do is take out the paranthesis so now we have 7t+3t. We can add 7 and 3 and noow we get 10 so the answer is 10t
