B) the ripples have a wavelength of 15 mm. given that their frequency is 1.4 x 10-2 khz,
calculate their speed in m/s. show your working.
0.014

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

read more on -

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

i'm on my way to history not a mistory.

c) power lifting, will be your answer.
