I might've gotten it wrong, but I think the answer is C. The object maintains a constant velocity because in the question, it says that the velocity and acceleration are going in the SAME direction, so it'd make sense if it was C. :)
Step #1
Set up a table of the runner's names and how long it takes them to run 100 meters.
Chart needed to track results in conducted experiment
Step #2
Lay out the measuring tape to equal the length of 100 meters.
Step #3
Shoot the starter pistol and began to time each runner individually, to get the correct times for each one.
Step #4
<span>After getting all the times for each runner, divide each time t by the distance of 100 meters, to find the rate of velocity. Then divide the change in velocity by time again to find </span>
a
Uniform Acceleration
Uniform acceleration will occur during the whole race-- with the hope that every runner runs at a constant rate of velocity.
You would calculate this by dividing the time by the distance traveled, or
t
<span>/100m.</span>
The reason satellites don’t fall from the sky is because they are orbiting Earth. Even though the satellites are thousands of miles away, Earths gravity still tugs on them. Gravity combined with the satellite's momentum from its launch into space, cause the satellite to go into orbit above Earth instead of falling back down to the ground.
P.S sorry if this isn’t the answer you were looking for have a good day
Not sure if you are saying the acceleration is positive or negative?
The equation you would use would be v=u+at, where v=final velocity u=initial velocity a=acceleration t=time. Using this if the acceleration is 2.51m/s^2:
v=2.98+(2.51*1.6)
v=6.996m/s
If the acceleration is -2.51 m/s^2:
v=2.98+(2.51*1.6)
v=-1.036m/s
