Question

An object is traveling in the positive x-direction and has an average acceleration of 9
meters per second squared with a change in time of 1 second. If the final velocity is 15
meters per second, then what is the initial velocity?
a. 6 m/s x
b. 6 m/s -x
c. 24 m/s x
d. 24 m/s -x
please help, thank u!

Answer 1

Answer:

the answer will be 24 m/s -x

Answer 2

Answer: Apply v = u + at

we get

u = v - at

u = 15 - 9

u = 6 ms^-1

thats your answer
