On Friday, February 27th, 2009 Mr. Manning began class by conducting a graded homework check. The homework had been to complete the **Roller Coaster/Energy Page**. After the check which was to show problem number 2 parts C and D, he gave us a daily question. The daily question was...

Three baseballs are thrown from the top of the cliff along paths A, B, and C. If their initial speeds are the same and there is no air resistance, the ball that strikes the ground below with the greatest speed will follow path

a.) A b.) B c.) C d.) either A or C e.) all strike with the same speed The answer was; e.) all strike with the same speed. After the daily question Mr. manning proceeded to review the **Roller Coaster/Energy Page** as well as the **K'NEX Coaster Activity**. This brought us to the end of class. Homework was to study for the test and to complete the review guide for Monday, March 2nd. In addition to this the **Machine Design Physics** worksheet for Tuesday, March 3rd. .
