Answer:
t = 9.5 seconds
Step-by-step explanation:
Given that,
The initial velocity of the projectile is 304 ft/s
The height of the projectile is given by :

For maximum height,
Put h' = 0

or

So, the time taken to reach the maximum height is 9.5 seconds.
Answer:
20, 21
Step-by-step explanation:
The number halfway between the middle two integers is the average of the four:
78/4 = 19.5
Then the four integers are 18, 19, 20, 21.
The 3rd and 4th integers are 20 and 21.
Answer:
0
Step-by-step explanation:
there is only blue marbles, yellow marbles, and red marbles. there are no purple marbles so you’d be unable to pull out a purple one no matter how many times you tried. so the probability would be 0
Divide it and then you have ur answer
We are given that:
vi, initial velocity = 24 m/s
v, final velocity = 15 m/s
t, time = 12 s
The formula for acceleration is:
a = (v – vi) / t
a = (15 – 24) / 12
<span>a = - 0.75 m/s^2 (deceleration)</span>
