A 0.140 kg ball hits a wall with a velocity of . It rebounds from the wall with a velocity of . In unit-vector notation, what are (a) the change in the ball's momentum, (b) the impulse on the ball, and (c) the impulse on the wall?

i believe it is b. what was the cause of the big bang

hope this !

because if the tool that you are using is not balanced it there would be false mass.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
