.. A uniform ladder of mass 10 kg and length 4 m rests with one end on a smooth horizontal hoor and the other end against a smooth vertical
wall. The ladder is kept in equilibrium, at an angle tan2 to the
horizontal, by a light horizontal string attached to the base of the ladder
and to the base of the wall, at a point vertically below the top of the
ladder. A man of mass 100 kg ascends the ladder.
If the string will break when the tension exceeds 490 N, find how far up
the ladder the man can go before this occurs.
What tension must the string be capable of withstanding if the man is to
reach the top of the ladder?​

the answer is to check all of them! they all apply well at least i think so!

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
