A bicycle racer is going downhill at 13.0 m/s when, to his horror, one of his 2.03 kg wheels comes off when he is at top of the hill. We can model the wheel as a thin-walled cylinder of diameter 0.85 m, with a moment of inertia of 0.367 kg-m2. (Neglect the small mass of the spokes). Consider its motion is rolling without slipping, and downhill angular acceleration of 2.3 rad/s2. What distance has the wheel traveled, in meters, when it is going at 43.3 m/s?

the closer the planet is to the sun, the larger the gravity

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
