Question 1 (5 points) A 15.22 kg ball moving at 9.129 m/s to the right collides with a 7.139 kg ball at rest. After the collision, the 15.22 kg ball moves at 4.810 mis to the right. What is the velocity of the 7.138 kg ball after the collision? 9.209 mis to the right 10.59 m/s to the right E 12.08 mis to the left 9.209 mds to the left o D 8.174 m/s to the right 8.174 ms to the left LO 10.59 m/s to the left h 12.08 m/s to the right

the answer is to check all of them! they all apply well at least i think so!

0.19 m/s and 0.45 m/s

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
