Question

A body is moving with variable acceleration (alpha) along a straight line.
The average acceleration of the body in the time interval t=0 to t=t° is?​

Answer 1

Answer:

a1 + a2 +a3 +a4........... ÷t°-t

Explanation:

let alpha=a

let the first acceleration be a1

as given,

acceleration is changing to time to time

therefore,

second acceleration=a2

third acceleration=a3

fourth acceleration =a4

and so on.

now, as we know,

average acceleration=mean acceleration

mean acceleration=a1 +a2 +a3 +a4..... ÷final time -initial time,

where final time=t°

initial time=t
