a car starts from rest and accelerates uniformly at 2m/s for 10second. what is its velocity at the end of 10 second?
V = Vo + a*t = 0 + 2*10 = 20 m/s.
Acceleration=2m/s
Time=10sec
V=Vo+a*t
0+2*10
0+20

and car starts from rest and acceleration uniformly at 2 m/second square for 10s .what is it's velocity at the end of 10s.
To find the velocity of the car at the end of the 10-second interval, we can use the formula for uniformly accelerated motion:
velocity = initial velocity + (acceleration * time)
Given that the car starts from rest (initial velocity is 0 m/s), accelerates uniformly at 2 m/s², and the time interval is 10 seconds, we can substitute these values into the formula:
velocity = 0 + (2 m/s² * 10 s)
velocity = 0 + 20 m/s
velocity = 20 m/s
So, the velocity of the car at the end of the 10-second interval is 20 m/s.
