Question

Consider the formula for the average velocity, v, of a moving particle. In the formula, d1 and d2 represent the distance traveled by the particle at times t1 and t2 respectively.

Answer 1

Answer:

Step-by-step explanation:

Let total time =t

Let d1 is the displacement of first half time and d2 is of second half time.

Total displacement(d)= d1+d2

Now v1=d1÷(t/2) => d1= v1.t/2 …..(1)

Similarly, d2= v2.t/2 …..(2)

now avg. velocity(v`) = (d1+d2)/t

put (1) and (2)

v`= (v1.t+v2.t)/2.t

v`= (v1+v2)/2

If T is the total time, distance moved in one half the time is v1*T/ 2, and in the other half time is v2*T/2 .

Total distance = (v1+v2)T/2.
