could someon give me general instructions about these kind of questions?

after that i got stuck...

Homework Statement 1)The value of k, so that the equations 2x2+kx-5=0 and x2-3x-4=0 have one root in common 2)The value of m for which one of the roots of x2 is double of one of roots of x2-x+m=0 3)If x2-ax-21=0 and x2-3ax+35 have a root in commom Homework EquationsThe Attempt at a Solution I...

Thanks for the help:wink:,

v=u+at (before reaching its highest point) 0=10+10t 1=t Then it would take 1s to come back to its starting point and v=u+at( after reaching the highest point) v=10m/s So basically both bodies start from the same point with the same vel. So the velocity before reaching the ground would be the...

OK wait a sec Is it that the second body gains the same velocity as the first on whenn it is100m high

But the distance traveled by both the bodies is different

OK let me see

1. The probleas statement, all variables and given/known data Two stones are projected from the top of a tower 100m high each with velocity of 10m/s. One is projected upward while the other is projected downward. Find the ratio of velocity's by with which they strike the ground. Homework...

Thanks for your advice

Nah i just posted that just in case somebody was interested you don't need to see the video because I gave a brief summary of what it's about

*came across

I across a video about how to be good enough at anything within 20 hours. It said that first to get rid of all barriers and the identify The small skills which are used in the thing you're trying to "become good enough at ",in this case in solving trigonometry questions, and grind them...

Thank you all for helping

OK got the mistake the ans now is 2(√2+1) Which is correct I was taking the denominator wrong thank you very much for pointing that out
