Question

what does the y - intercept represent?
a. the number of seconds it took for the coin to reach the ground
b. the initial height from which the coin was shot with the sling shot
c. the rate at which the coin traveled through the air
d. the initial velocity of the coin when shot with the sling shot

Explanation:

The y - intercept of a height - time graph is the height value when time \(x = 0\). In the context of the coin being shot from a slingshot, when \(x = 0\) (the start of the motion), the height is the initial height from which the coin was shot.

Answer:

B. the initial height from which the coin was shot with the sling shot
