Reduce friction because friction just makes things harder
Answer: Not 100% sure but I believe the answer is B.
Hope this helps! ^^
Displacement (between time 0 and time 25) is the area under the velocity time curve, i.e. ∫ vdt.
Here, v(0)=10, v(25)=34 (approx.)
Therefore
displacement = (1/2)(10+34 m/s)*(25-0) s [ trapezoid area ]
=550 m
He should confront her about it and if after that point she continues report it to the chess team
Acceleration is the rate at which velocity changes.

Simply equate the two.

<span>dV / dt = F/m </span>
<span>F*dt = dV * m </span>

The impulse you give any object (average force * time elapsed) is equal to its change in momentum (mass * change in velocity).</span>
