Question

andy was on top of a building. he threw a ball up in the air and watched it hit the ground. the path of the ball is modeled by the graph. which choice best approximates the time it took for the ball to hit the ground?
a 1 second
b 8 seconds
c 12.5 seconds
d 18.5 seconds
e 14.5 seconds

Explanation:

Step1: Analyze the problem context

The problem is about the time - of - flight of a ball thrown upwards from a building. We need to choose the most reasonable time among the given options.

Step2: Consider physical possibilities

A ball thrown upwards will take some time to go up and then come down. A time of 1 second is too short as it doesn't account for the upward motion and then the downward motion. Among the other options, 8 seconds is a more reasonable estimate compared to 12.5, 14.5 and 18.5 seconds which seem rather long for a typical ball - throwing scenario from a building.

Answer:

B. 8 seconds
