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?
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
v(t) = v0 + at
Now just plug in your numbers
think about it. v increases by 120m/s every second...
Thanks sir... got ans=121
But my text is saying ans=112
Thanks sir... I will stil try it out but what's ur own final answer to this?
that's a joke, right? Go back and read what I wrote.
To find the final velocity of the object after 100 seconds, we can use the equation of motion:
Final Velocity = Initial Velocity + (Acceleration x Time)
Given:
Initial Velocity (u) = 100 m/s
Acceleration (a) = 120 m/s^2
Time (t) = 100 seconds
Plugging in these values into the equation, we get:
Final Velocity = 100 m/s + (120 m/s^2 x 100 seconds)
First, we multiply the acceleration and time:
Final Velocity = 100 m/s + (12,000 m/s)
Then, we add the initial velocity and the result of the multiplication:
Final Velocity = 100 m/s + 12,000 m/s
Final Velocity = 12,100 m/s
Therefore, the velocity of the object after 100 seconds will be 12,100 m/s.
