If an object is thrown straight up in the air with a velocity of 160ft/sec then it's h(t) above the ground t seconds later us given by the formula:

Question

h(t)= -16t^2 + 160t find the height after 4 and 5 second

Answer 1

h(4) = -16(4²) + 160(4)

h(4) = -256 + 640

h(4) = 384

 

You tell me what h(5) is.
