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? 30 meters 40 meters 50 meters 60 meters

Answer is 50 meters

Step-by-step explanation:

Solution:

Height of the building (h)= 90 meters.

Time taken by the ball to reach the ground (t) = 3 seconds

According to the statement;

h = kt²

90=k(3)²

90=k(9)

90=9k

Divide both the sides by 9

k=10

h=kt²

Put the value time (t)=2 in the equation

h=10(2)²

h=10(4)

h=40 meters

Distance from the ground = 90 - 40

=50 meters.

Thus the correct option is 50 meters
