Question

@Abhisar
The diagram shows a square block at four positions along a track. The track is frictionless between points A and B, and rougher elsewhere.

Initially, the block is held in place against a spring by a horizontal external force. Then the external force is removed, and the block is projected forward. It travels down a ramp and across the rest of the track. It slides a distance S to a stop at point D.

To calculate the height h of the ramp, values for which set of variables are necessary? (Note: Vk refers to the speed of the block at a point shown in the diagram.)

Answer 1

Options
V2 and the mass of the block
V2 and the spring constant
V1, S, and the mass of the block
V1, S, and the coefficient of friction of the rough surface.

Answer 2

Answer 4

Sorry for being so slow...have lots of notifications to handle :(

Answer 5

its okay

Answer 6

What do u think ?

Answer 7

I think its spring constant and v2

Answer 8

How will u find h ?

Answer 9

Isn't it v^2/2g

Answer 10

\(\huge\sf Brilliant !\)

Answer 11

So we just need the velocities but v1 and v2 isn't an option

Answer 12

That's were m stuck too !

Answer 13

Is there another equation for h

Answer 14

@kropot72 can u help ?

Answer 15

Not sure what to do

Answer 16

Can i answer this one tmrw ?

Answer 17

Sure im gonna put up another question with this diagram
