The mass of the toy truck in the figure below is three times the mass of the stroller and are united in its rear by a string and a compressed spring. When the spring breaks, the stroller moves left at 8 m/s. What is the velocity imparted to the toy truck?

i. like it i'm gonna edit it tomorrow

c)as speed changes, wavelength and frequency change.

everything changes!

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
