List the following items in order of decreasing speed, from greatest to least: (i) a wind-up toy car that moves 0.15 m in 2.5 s. (ii) a soccer ball that rolls 2.3 m in 0.55 s. (iii) a bicycle that travels 0.60 m in 0.075 s. (iv) a cat that runs 8.0 m in 2.0 s. knight, randall d., (professor emeritus). college physics (p. 28). pearson education. kindle edition.

(iii) > (ii) > (iv) > (i)

Explanation:

Part (i):

Part (ii):

Part (iii):

Part (iv):

From the above calculations, we have

So, the speed in the parts mentioned arranged in decreasing order as follow:

(iii) > (ii) > (iv) > (i)

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
