We should first calculate the highest point that ball reaches.
y' = 40 - 32t = 0
t = 40/32 = 1,25s
y = 25 feet.
To calculate average velocity we use simple formula:
Vav=s/t where s is traveled distance by the time t.
for t=2 we calculate y
y = 16
(i) for t = 2,5 y = 0
Vav = 16/0.5 = 32 feet/s
(ii) for t = 2.1 y = 13.44
Vav = 2.56/0.1 = 25.6 feet/s
(iii) for t = 2.01 y = 15.7584
Vav = 0.2416/0.01= 24.16 feet/s
it seems like the answer would be 24 feet/s. There is a way to calculate that.
You multiply 212 by 12 to get an answer. The answer is 2,544
Its a object to determine the space or width around something.
Breaker D cuz it says 18 and that’s the highest temp
A physical property can be seen or a change in color.
The answer is B because you can see when wood is rotting.
