A 15kg boulder is going 55 m/s West when it collides with an 8kg bolder going 3 m/s East. They smash together inelasticly. Ignoring friction and heat losses what is their combined velocity after the smash up?

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

it was given as a lesson and guide for prayer.

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
