Chloe's mother threatens to ground her for life if she comes home after curfew. Chloe knows her mother cannot follow through with that punishment and comes home late anyway. Chloe's mother should have used which tip for effective punishment? She should have used a punishment that is really punishing.

She should have punished Chloe immediately after the bad behavior occurred.

She should have remained calm while punishing Chloe to eliminate the chance of abuse.

She should have punished Chole each and every time the bad behavior occurred.

The third option

Explanation:

The third option would be the best choice because while staying calm, Cloe will feel guilty and her mother will not be stressed. Staying calm also shows that Cloe's mother loves her but is disapointed, making Cloe think twice about her actions, while yelling and whipping only puts fear into her mind.

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
