The plan: Video clip of the day Movember Review of motion Quiz information Acceleration

Movember: I am going to let you people decide. –There are three options I’m considering. –They will be shown in the next 3 slides. Each cent counts for a vote. 1 penny = 1 vote. 1 toonie = 200 votes.

Movember: Collecting voting money until Friday. Collecting money all month for the cause. All money given will be directly donated to the Cancer Society My goals –Minimum of 50 dollars raised –To out do Mr. Cooper either in beard or money raised..

Constant Acceleration: v f = v i + at v f = Final velocity in meters per second (m/s) v i = Initial velocity in (m/s) a = acceleration in m/s 2 t = time in seconds (s)

Example #1 A car accelerates from 0m/s to 20m/s [N] in 4 seconds. Find the acceleration in this situation.

Example #2: Haley’s ball is rolling away from her at 2m/s [E]. It start to accelerate down a steep hill at the rate of 4m/s 2 [E] and continues to do so for 4 seconds. What is the balls final velocity?

Try this: Tim’s initial velocity is 20m/s [W]. He hits the gas and accelerates at 2m/s 2 [W] for 5 seconds. How fast is Tim going after his acceleration?
