Question

what is "initial velocity" and how do we find it? Like whats the difference between that and "average velocity"

Answer 1

Initial velocity means the velocity with which the body started.
Initial velocity when the object starts from rest is 0

Answer 2

Initial velocity is the velocity of a moving body at the starting.
if we are given final velocity, acceleration and the time for which the body is accelerated we can find the initial velocity.
v-u=at
u=v-at

Answer 3

Make u the subject of the formula in v=u+at which is a physics eqn.
v=final velocity
u=initial velocity
a=acceleration
t=time
ie if you have the variables

Answer 4

while Average velocity is the displacement/time

Answer 5

ok so if the question is asking what Find the initial velocity for an object that moves along a straight line so that at time "t" measured in seconds, its distance from a fixed point O is given by x= 8 -2t -t^2

Answer 6

differentiate this to find velocity
x=8-2t-t^2
dx/dt=-2-2t
v=-2-2t

Answer 7

put t=0 to get initial velocity
v=-2 initial velocity

Answer 8

ohhhh i seeee arigato

Answer 9
