Answer:
Maximum height of the ball, h(t) = 27.56 m
Explanation:
It is given that, a ball is shot from the ground straight up into the air with initial velocity of 42 ft/sec.
The height of the ball as a function of time t is given by :
h₀ is initial height, h₀ = 0
So, .........(1)
For maximum/minimum height,
...(2)
t = 1.31 s
Differentiating equation (2) wrt t
h''(t) = -32 < 0
So, at t = 1.31 seconds we will get the maximum height.
Put the value of t in equation (1)
h(t) = 27.56 m
Hence, this is the required solution.
Answer:
degrees
Explanation:
Eels have been recorded to spin at up to 14 revolutions per second when feeding in this way
So the angle the eel rotate is going to be
Camera record 120 frames per second
time taken for 1 frame record
eel rotates
degrees in 1 second
so:
eel rotetas degrees
