Tom and ted are sitting on separate chairs that have wheels. tom pushes ted and, in turn, he starts moving too. in which direction does tom move?

They move in opposite directions.

Explanation:

As we know that they both apply force on each other and here they have no external force on them

So here we can say that

now we will have

now we can say

so we have

so here both have equal and opposite momentum so then both will move in opposite direction to each other

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
