Atextbook of mass 2.10 kg rests on a frictionless, horizontal surface. a cord attached to the book passes over a pulley whose diameter is 0.100 m , to a hanging book with mass 2.99 kg . the system is released from rest, and the books are observed to move a distance 1.26 m over a time interval of 0.790 s . part a what is the tension in the part of the cord attached to the textbook? =9.66n part b what is the tension in the part of the cord attached to the book? take the free fall acceleration to be = 9.80m/s^2 =15.5n part c what is the moment of inertia of the pulley about its rotation axis? take the free fall acceleration to be = 9.80 m/

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

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.
