Question

A box is tossed upward from a cliff that is 12 meters high, at a speed of 11 meters per second. The height of the box in meters is given by h(t)=−4.9t2+11t+12 where t is seconds. What is the height of the box at 1 second?

Answer 1

18.1 meters

Explanation:

h(t) = -4.9t² + 11t + 12

When t = 1:

h(1) = -4.9(1)² + 11(1) + 12

h(1) = -4.9 + 11 + 12

h(1) = 18.1

The height of the box is 18.1 meters.
