Question

Yea, gonna need some help. Thanks

Answer 1

t = 3.48 s

Step-by-step explanation:

The time for the maximum height can be calculated by taking the derivative of height function with respect to time and making it equal to zero:

`h(t) = -16t^2+v_ot+h_o\\\\(dh(t))/(dt)=0=-32t+v_o\\\\v_o = 32t`

where,

v₀ = initial speed = 110 ft/s

Therefore,

`110 = 32t\\\\t = (110)/(32)\\\\`

t = 3.48 s
