Question

A particle moves in a straight line with initial velocity u. and uniform acceleration a if the sum of the distances travelled in t th second and t+1 th second is 100 cm then it's velocity after t seconds in cm/s is​

Answer 1

See, initial velocity =u

accelaration =a

t=100-t+1 or t+t+1=100

=2t+1=100

2t=99

t=99/2

so

v=u +at

= u +a×99/2

v= u+99/2a cm/s

I don't know whether this ans is correct... but rely on me process is correct...
