2. a block of mass 100. kg is placed on an inclined plane with a
slope of 35.0° to the horizontal, and is connected to a second
hanging block of unknown mass by a cord over a small
frictionless pulley. the coefficient of kinetic friction is 0.300.
a. calculate the mass of the hanging block if the 100.kg
block slides up the plane at a constant velocity.

b. calculate the mass of the hanging block if the 100 kg block slides down the
plane at a constant velocity

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.

answer is slate

hope this
