Answer:
It would take 2 second to reach its maximum height.
The maximum height of the ball is 43.6 meters above the ground.
Step-by-step explanation:
Consider the provided function.
The above function's graph is a downward parabola and the maximum of the downward parabola is at its vertex.
We can find the x coordinate of the function using the formula:
Substitute a=-4.9 and b=19.6 in
Hence, it would take 2 second to reach its maximum height.
Substitute x=2 in above formula.
Hence, the maximum height of the ball is 43.6 meters above the ground.
Answer:
It will take 2.6 hours by Daniel to catch up with Frank.
Step-by-step explanation:
Let Daniel will catch up with Frank after t hours.
Now, Frank will go 13 miles in hours.
So, the distance traveled by Frank in (t + 0.228) hours with 45 mph speed will be equal to the distance traveled by Daniel in t hours with 50 mph speed.
Hence, 45(t + 0.288) = 50t
⇒ 5t = 13
⇒ t = 2.6 hours.
Therefore, it will take 2.6 hours by Daniel to catch up with Frank. (Answer)
