Question

A particle moving in a straight line initial velocity u and uniform acceleration f. If the sum of the distance travelled in t^th and (t + 1)^th seconds is 100 cm, then its velocity after t seconds in cm/s is

Answer 1

 Δs=vΔt+12a(Δt)2.
The velocity after ts is =vcms−1.
Δt=t+1−t=1s. The acceleration is a=fcms−2.
The distance is Δs= 100c ...
