A particle moving with uniform acceleration from a to b

Asked by admin @ 02/08/2021 in Physics viewed by 308 People

A particle moving with uniform acceleration from A to B along a straight line has velocities V1 and V2 at A and B respectively if c is the midpoint between A and B then determine the velocity of the particle at c

plz help me guyz

I think this is likely to be....
sq (v2)-sq (v1)=2as. ....
from this
s=sq (v2)-sq(v1)/2a
so s/2=sq (v2)-sq (v1)/4a. .........divide both sides for middle distance.... (1)
now distance=speed×time
(1)= v×time. ..... (2)
now find t from v=u+at...
nd put in eq 2
then v= (v2+v1)/4
