Question

determine the maximum acceleration of the train in which a box lying on its floor will remain stationery, given that the co efficient of static friction between the box and the train's floor is 0.15​

Answer 1

Answer:

huh?

Explanation:

sorry but i dont understand

buy pls can you folllow me?

Answer 2

As per the question,

Its given that the acceleration of the box lying on the floor is due to the static friction between box and the train's floor as the box lying is always in stationary condition.

Therefore,

Force applied on box is always less than static frictional force.

Since,

Static frictional force is given by

Where,

R = mg

Now,

Force applied = ma

Therefore,

Therefore,

The maximum acceleration of the train in which a box lying on its floor will remain stationary = 1.47 ms⁻²

Hope this answer will help you.
