Question

The function relating the height of an object off the ground to the time spent falling is a quadratic relationship. Travis drops a tennis ball from the top of an office building 90 meters tall. Three seconds later, the ball lands on the ground. After 2 seconds, how far is the ball off the ground?

Answer in meters please

Answer 1

Answer:

50

Step-by-step explanation:

h = kt^2

90 = k (3)^2

k = 10

h = 10× 2^2 = 40

Distance from ground = 90-40 = 50

Answer 2

Answer:

90- 40=50 is the answer
