Problems # 1, 5, 7 Pg 105-106
1.) An 873-kg dragster, starting from rest, attains a speed of 26.3m/s in .59s
a.) Find the average acceleration of the dragster during this time interval.
b.) What is the size of the average force on the dragster during this time interval?
c.) Assume the driver has a mass of 68kg. What horizontal force does the seat exert on the driver?
d.) Is the driver's mass in part C an inertial mass or gravitational mass?
5.) After a day of testing race cars, you decide to take your own 1550-kg car onto the test track. While moving down the track at 10m/s, you suddenly accelerate to 30m/s in 10s. What is the average net force that you applied to a car during the 10-s interval?
7.) A force of -9000N is used to stop a 1500-kg car traveling at 20m/s. What braking distance is needed to bring the car to halt?

Today in physics
Today in physics, we got our Nature of Light Tests back & corrected it. Ms. K gave us some time to finish The Nature of Light Theory Sheet & we corrected that too. All the answers to the Nature of Light Test & Theory Sheet are post up by Ms.K, fix your mistakes. You can read ahead in The Nature of Light booklet because we will be discussing it tomorrow.
And the next scribe belongs to Kimberley Tran.
& HAPPY HALLOWEEN EVERYBODY!! get lots of candy :)

hello my name is Jennifer I am today's scribe.
Today we had a TEST on Waves In One Dimension 0_0
After the test we got a new green booklet called Waves in Two Dimensions & read up to page 6 we also got an exercise on Wavefront's to finish by tomorrow. That is all we did today (:
finally the scribe for tomorrow is . . .
