All Students Homework

Midyear review assignments are to done on clean sheets to be turned in on date due in schedule. Therefore, when you do review assignments, ALSO DO THEM ON THE REVIEW PACKAGE SO YOU CAN STUDY FROM THEM AND CHECK YOUR ANSWERS WHEN I POST THE SOLUTIONS!

Other homework is also due on the due date so I should be seeing work on rotational motion form period 8, on vectors and 2 dimensional motion from periods 2 and 4  and on oscillations and waves from period 6.

 Honors Page 87 problem 2. You were supposed to do it graphically with protractor and ruler. Analytically,  the x component is 85 m +45 cos 30 degree = 124 m and the y component = 45 cos 60 degrees = 22.5 m  The magnitude of the displacement is therefore the sqrt (x squared + y squared) = sqrt of (124  squared  + 22.5 squared ) = 126 m
