More people end up in u. s. emergency rooms because of fall-related injuries than from any other cause. at what speed v would someone hit the ground who accidentally steps off the top rung of a 9.00 ft tall stepladder? (that step is usually embossed with the phrase "warning! do not stand on this step.") ignore the effects of air resistance. let the +y direction point vertically upward and the origin be on the ground.

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

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
