An object is launched into the air. the projectile motion of the object can be modeled using the function h(t) = –16t2 + 72t + 5, where t is the time in seconds since the launch and h(t) represents the height in feet of the object after t seconds. what is true about the projectile motion of this object? check all that apply.

Step-by-step explanation:

Given that an object is launched into the air. The projectile motion of the object can be modeled using the function

h(0) = 5

i.e. initial height =5

h'(t)= -32t+72

Hence velocity =0 when t = 9/4=2.25 seconds

After 2.25 seconds it will start coming down

Maximum height = h(2.25) = -16(2.25)^4+72(2.25_+5

= -81+162+5

=86

it is a secret for it not to be compromised sorry
