Same speed, because mass is neglected. The things that affect the speed are the distance and speed of the rock.

Well you have to minus the 4.5 to 5.2 and the answer to that would be -11.5 and calculated that to be 4.5

You are conducting an experiment inside a train car that may move along level rail tracks. A load is hung from the ceiling on a

Triss [41]

Here the weight is hung from the thread inside the ceiling of train

now the FBD of train is analysed

We can say

$Tcos\theta = mg$

$Tsin\theta = ma$

now by ratio of two equations we have

$a = gtan\theta$

this shows that train must be in accelerating condition due to which the thread is making an angle with the vertical

now we will have

2 The train is not an inertial frame of reference.

Since train is accelerating so it must be non inertial frame

5 The train may be moving at a constant speed in a circle.

Since its moving in circle so it is in accelerating condition

8 The train must be accelerating.
