A 1.0 kg mass is attached to a string and moves in a horizontal circle with a radius of 1.0 m at a rate of 4.0 rev/s. a.) Find the centripetal acceleration of the mass.
b.) Calculate the magnitude of the centripetal force acting on the mass.
c.) What is the direction of the centripetal force?

answer; how far out of place which the object finished relative to the starting location;

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

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
