Answer:
The instantaneous velocity after eight seconds is 9 m/s
Step-by-step explanation:
Given as :
The ball shot upward with velocity of 15 m/s
The height of the ball after t sec is given as h(t) =
Now, The instantaneous velocity after 8 sec =
Or, The instantaneous velocity =
or, The instantaneous velocity =
Now at t = 8 sec
The instantaneous velocity = 5 + 4 = 9 m/s
Hence The instantaneous velocity of ball at t = 8 sec , is 9 m/s Answer
Answer:
C) cannot be simplified
<u>Explanation</u>
We want to simplify the radicals:
We can rewrite this as exponents:
Since the base are the same but are subtracting, we do not have any rule of indices for subtracting unlike indices .
Therefore the expression cannot be simplified further.
