Is it the same as the velocity of the platform itself?

Homework Statement A stone is dropped from a balloon at an altitude of 300 metres. How much time is required for the stone to reach Earth if: (1) Balloon is ascending with a velocity of 5 m/s, (2) Balloon is descending with a velocity of 5 m/s (3) Balloon is stationary Disregard air...

Ahh... I didn't realize that the equation is only for uniformly accelerated motion. I've got the answer now. Thanks!

Change in position/Change in time?

Homework Statement A ship goes from A to B at v_1=10 km/h and from B to A at v_2=16 km/h Find: (1) the average velocity of the ship, and (2) the velocity of the river current. Homework Equations v_{avg}=(v_1+v_2)/2 v_{AC}=v_{AB}+v_{BC} The Attempt at a Solution...

So, you mean that I have to fully master the maths so that I can apply it to the physics? If that's what you mean, then any tips that you can provide? I would really like to start with physics early since it's my passion.

No. That's not what I mean. I meant that can I get a rough idea of what the levels are covering? For example, level XX is covering Precalculus or level YY is covering Calculus. I would like to know the level's standard in terms of US(?) system. Another thing I want to ask is that what is the...

Hi all. This is my first post, so I hope this is the correct place to post. I have been studying maths at Kumon for the past years. I just want to see if I have covered the basic maths needed for studying physics (start with MIT 8.01 maybe?). When I browse through this forum, I have no idea...
