Aball is dropped off the side of a bridge. after falling 1.55 s, what is its velocity?

Use the basic kinematic equation of

Final velocity = initial velocity + acceleration * time (shown in image)

simply plug the numbers in to get

Velocity(final) = 0 + -9.80 m/s^2 * 1.55 s

to give us

-15.19 m/s for our final velocity

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
