10 points) A rubber ball and a lump of putty of the same mass m = 0.05 kg are thrown with the same speed v=10.0 m/s in positive x-direction against a vertical wall. The ball bounces back with the same speed v’=10.0 m/s in negative x-direction. The putty sticks to the wall. Which of the two objects (rubber ball and a lump of putty) experiences the greater momentum change?

the ball experiences the greater momentum change

Explanation:

You have to take into account that momentum change is given by

where vf and vb are the speed of the object after and before the impact.

In the case of the ball you have

where the minus of vf is included due to the motion is in an opposite direction regarding with vb

And for the lump

Hence, the ball experiences the greater change

hope this helps!!

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
