A 0.350 kg ball of clay is thrown and sticks to a 1.2 kg block of wood initially at rest on a horizontal frictionless surface. If the clay was initially moving toward the wood with a speed of 25 m/s, then calculate the speed of the clay-block system following their collision.

A. to determine if humans can explore mars safely

Make them both to where they have the denominator of 18that makes 3/2 equal 27/18 and 1/9 equal 2/18so now you have  27/18x+5=2/18subtract 5 from the other sideso now you have 27/18x+2/18-5then subtract 2/18 from 27/18 to get 25/18x=-5then divide 25/18 by -5 and your answer will be  -5/18

Idon't understand is there supposed to be a list or something if there is pm or add in under this message i will do my best to .

Blue light reflected from the ball enters human eyes.
