This week we are learning about projectile motion and finishing our full lab writeup of vector force table components. We will be discussing how things travel in two dimensions and learn the math which helps us explain and predict this motion. The simulation below will be used in class.

I have provided you with a bunch of resources because these will be the first longer multistep problems. Please watch the videos when you can, aka on your phone during bus rides, to help with staying up with the material.

Glenns HW6: Ch 3: 39, 42, 43, 45, 47, 51, Due: Wednesday Oct 8,

Glenns HW7: Ch 3: 52, 56, 74, 80, 84, 85 Due Friday Oct 10th

Glenns Worksheet: Due Oct 13 (WS above)

Warsaw Worksheet due Tuesday Oct 14th, (WS above)

Warsaw: Ch 3: 39, 42, 43, 45, 47, 51, 52, 56, due Thursday Oct 16th

Vy (Velocity in the Y direction)

Vx (Velocity in the X direction)

Vx = Vi * cos(angle)

Vy = Vi * Sin(angle) - 9.8(t)

Vy=at

t=2Vy/a (it is double because one t is just how long it takes to get to the top. It takes just as long to fall again)

Range = (sin(2*angle)(Vi)^2) / 9.8

Vi= sqrt(D*9.8/sin(2*angle))
