Not sure if this is what you’re looking for. Let me know if I can clarify anything.
The height function would be s(t) = -16t^2 + 64t + 32.
Maximum height ---> set s'(t) = 0.
-32t + 64 = 0. ---> t = 2. s(2) = -16(2)^2 + 64(2) + 32 = the maximum height is 96 feet.
To find the velocity when it hits the ground, set s(t) = 0.
-16t^2 + 64t + 32 = 0. Divide by -16.
t^2 - 4t - 2 = 0. The only positive solution is x = 4.45.
s'(4.45) = -32(4.45) + 64 = It's going -78.4 feet/second when it hits the ground.
Answer:
A. The forces are the same size and in opposite directions.
Explanation:
Just as an opposite number will cancel a number: -1 +1 = 0, so an opposite force will cancel a force, with the result that the net is zero.
Answer:
Explanation:
Given data
Speed v=2650 km/h
Radius r=85.0 km
To find
Centripetal Acceleration
Solution
As centripetal acceleration is given as
where
v is velocity
r is the radius
Substitute the given values in eq(i)
