A0.2kg mass attached to the end of a spring is whirled in a vertical circle by a student. at some position, the mass experience a downward force of –62jn and a horizontal force 38i n. determine its acceleration in the position.

a=363.593m/s*2   we have rectangular component of force so we first find force resultant by square both component then square root and finally divide with 0.2 kg mass

do you have a formula possibly

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
