Question

a particle is moving in such a way that its velocity is V1 for time T1 and then after new velocity is V2 for T2 time .assume particle is moving along a straight line.the average acceleration is

Answer 1

HEY BUDDY..!!!

HERE'S THE ANSWER..


______________________

▶️ Acceleration is rate of cahange of velocity

⏺️ According to statement

=> Acceleration = ( final velocity - initial velocity )/ change in time

=> Acceleration = ( v2 - v1 ) / ( t2 - t1 )


HOPE HELPED..

Answer 2

av acceleration= change in velocity/total time 

change in velocity=v2-v1
total time= t1 +t2
hence avg acceleration=( v2-v1)/(t1+t2)
