Kate, a bungee jumper, wants to jump off the edge of a bridge that spans a river below. kate has a mass m, and the surface of the bridge is a height h above the water. the bungee cord, which has length l when unstretched, will first straighten and then stretch as kate falls. assume the following:
(a)the bungee cord behaves as an ideal spring once it begins to stretch, with spring constant k.
(b) kate doesn’t actually jump but simply steps off the edge of the bridge and falls straight downward.
(c) kate’s height is negligible compared to the length of the bungee cord. hence, she can be treated as a point particle. use for the magnitude of the acceleration due to gravity.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

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

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
