Question

A body moving fromA to B and there is between point c. and c is not mid point of these straight path. and AtoC distance is xby2 and cto b is x by2 and AtoB is x and a to c velocity is v1 and c to b is v2 find average velocity​

Answer 1

Given that body is moving with constant acceleration.

Lat the total distance AB be 2x and the acceleration be a.

⇒AC=BC=x

Speed at A is u and speed at B is v.

Let the speed at C be z.

⇒z2=u2+2ax and v2=z2+2ax

⇒z2−u2=v2−z2

⇒2z2=u2+v2

⇒z=2u2+v2
