A spring attached to the ceiling is stretched 2.45 meters by a four kilogram mass. The mass is set into motion in a medium that imparts a damping force numerically equal to 16 times the velocity. If the mass is pulled down two centimeters and released, the solution for the position is

i think the answer is a, hope this is right, that would be my best guess.

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

e/c, where e is its total energy

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
