A body is dropped from a certain height. During it’s descent it’s average velocity (<v>) for the duration of motion and its instantaneous velocity (v) are related as |
A) <v> greater than v | B) <v> less than v |
C) <v> equal to v | D) any of these |
A body starts from rest and accelerates for a certain time and travels with a uniform velocity for some more time and then slows down to rest. During it’s motion it’s average velocity (<v>) and its instantaneous velocity (v) |
A) can be equal while it is accelerating | B) can be equal while velocity is uniform |
C) can be equal while it is slowing down | D) none of these |
A body starts from rest and accelerates for a certain time and has a uniform velocity for rest of its motion. During it’s motion it’s average velocity (<v>) and its instantaneous velocity (v) |
A) can be equal while it is accelerating | B) can be equal while velocity is uniform |
C) |
D) v is greater |
A body starts from rest and is accelerating uniformly. If v is it’s velocity at any instant, it’s average velocity will be |
A) v | B) v/2 | C) 2v | D) any of these |
A body starts from rest and has a non uniform acceleration. If v is it’s velocity at any instant, it’s average velocity will be |
A) v | B) v/2 | C) 2v | D) can be any of these |
