Answer the following questions
2x2 = 4M
1. How is the average velocity different from instantaneous velocity?
2. A vehicle travels half the distance L with speed Vi and the other half with speed
V2, what is the average speed,​

Answer 1

Answer:

1) Average velocity of a body is defined as the change in position or displacement (Δx) divided by time interval (Δt) in which that displacement occurs.

Average velocity of a body is defined as the change in position or displacement (Δx) divided by time interval (Δt) in which that displacement occurs.The instantaneous velocity of a body is the velocity of the body at any instant of time or at any point of its path.

2) avg. speed= total distance

total time

L = L = 2v1v2

L L L + L v1+v2

2 + 2 2v1 2v2

v1 v2
