A box is tossed upward from a cliff that is 15 meters high, at a speed of 4 meters per second. The height of the box is given in
meters by h(t)=−4.9t^2+4t+15 where t is seconds. What is the height of the box at 1 second?
1 answer:
Answer:
14.1m above the sea level.
Step-by-step explanation:
h(t)=−4.9t²+4t+15, t in seconds
When t=0s, h(0)=15m (height of cliff), so it means that h is measured from the sea level.
After 1 second: h(1)=-4.9+4+15=14.1m above the sea level.
