The wall of a room are representations of what basic element of geometry is “plane”
1.)
Velocity is in m/s, and acceleration is in m/s^2 like you said. Because of this, we can calculate this by dividing the speed by the time it took to get to that speed.
(20 meters/second) / 10 seconds = 2 meters/ second^2
2.)
Same thing with the first one.
(100 meters/second) / 4 seconds = 25 meters / seconds^2
Distance = rate multiplied by time so do the inverse of that
As a fraction,
35/42, simplified, 5/6
answer=5/6
hope this helps....
