Awheel on a game show is given an initial angular speed of 1.12 rad/s . it comes to rest after rotating through 0.75 of a turn.

part a. find the average torque exerted on the wheel given that it is a disk of radius 0.61 m and mass 5.4 kg.

part b. if the mass of the wheel is doubled and its radius is halved, will the angle through which it rotates before coming to rest increase, decrease, or stay the same?

(assume that the average torque exerted on the wheel is unchanged.)

will increase? will decrease? will stay same?

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.
