Answer:
Air-7sec
Water-5sec
Explanation:
-The average speed of the stone in air is given as , average speed in water is . And the total distance is .
Let speed in air be and in water and is displacement:
#Solving the simultaneous equations:
Time in air is 7sec, Time in water is 5sec
tectonic plates rubbing against each other.
It can be fire ice water grass and stuff like that
height of the ball is given as a function of time
it is given by equation
here in order to find the maximum height we will use the concept of calculus where the maximum value of function will exist when its derivative becomes zero.
so here we can say
now we will put t = 3 in the given equation
So the maximum height will be h = 144 ft.
