Pomegranate is thrown from ground level straight up into the air at time t=0 with velocity 176 feet per second. its height in feet at t seconds is f(t)=−16t2+176t. find the time it hits the ground and the time it reaches its highest point.

Position is given as function of time

now rate of change in position with time is given as

so when it reached to highest point its velocity will be zero

so it will take 5.5 s to reach the highest point

Also we know that it took same time to reach back on ground too

So total time taken by the object to come back is given by

so it will take 11 s to reach back on ground

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow
