The of an objects is give relative ro an origin

The position of an object is given relative to an origin.

'Origin' here simply means a standard point of reference. For example, when we plan to go to a supermarket in our locality, we think of how many streets or blocks away that place is from our house. Here our house serves as the origin about which we locate the position of several stores.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

i believe the answer is a hope it and is correct
