Question

An object at 100 m/s accelerates at a rate of 120 m/s 2 . What will the velocity of this object be after 100 seconds?

Answer 1

v(t) = v_₀ + at
Now just plug in your numbers

think about it. v increases by 120m/s every second...

Answer 2

Thanks sir... got ans=121
But my text is saying ans=112

Answer 3

neither one is even close
100 + 120*100 = 12100

112 = 100 + 1.20 * 10.0
Is that maybe what you meant?
Maybe not, but you are clearly missing some decimal points

Answer 4

Thanks sir... I will stil try it out but what's ur own final answer to this?
