Answer:
Maximum height is 29 ft
Time to reach the ground is 2.60 seconds
Step-by-step explanation:
We are given equation of height as
Maximum height:
we know that at maximum height
velocity =0
so, we will find derivative
and then we can set it to 0
and we solve for t
now, we can set it to 0
and then we can solve for t
now, we can plug t into height equation
Time to reach the ground:
we know that at ground
height=0
so, we can set h(t)=0
and then we can solve for t
we can use quadratic formula
Since, time can never be negative
so, we will only consider positive time
