A ball is thrown into the air with an initial velocity of 22 meters per second. The quadratic function h(x)= -4.9t square +22t+5
.5 represents the height of the ball above the ground, in meters, with respect to time t, in seconds. Determine h(3) and explain what it represents
1 answer:
Answer:
Height of the ball after 3 seconds = 27.4 feet.
Step-by-step explanation:
h(t) = -4.9t^2 + 22t + 5.5
h(3) means the height of the ball at time 3 seconds after the ball was thrown.
h(3) = -4.9(3)^2 + 22(3) + 5.5
= 27.4 feet
