Carlos attempts to get a refrigerator magnet to stick on the s end of a bar magnet. he is unable to do so and states that the bar magnet is broken. evaluate his argument: is this correct or incorrect? explain.

It is incorrect.

Explanation:

Refrigerator magnets are actually multiple layers of magnets, and they are stacked using opposite polarities, so the south end of the magnet might be under a north, so if he puts the magnet on its side it will probably attract.

the force on the thing and the distance the force moves the thing

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
