in the figure shown, the coefficient of kinetic friction between the block and the incline is 0.40. what is the magnitude of the acceleration of the suspended block as it falls? disregard any pulley mass or friction in the pulley.

option number c is the right answer.

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 really dont know but i will try okay.

so i think u would just add all them up and get your answer..

the answer is 100. i just did this lesson and got a 100% on it. : )
