For each of the problems below, you will need to draw a graph to find the solution. 3. A driver who is moving at 15 m/s, sees a stop light and puts on the brakes 30 m before an intersection.
a) What acceleration will the driver have to have to stop before entering the intersection?
b) How much time will it take to stop the car?

4. A boy standing on a bridge spits into the water below. He hears the splash 1.5 seconds later. How high is the bridge?

5. A ball is thrown upwards at 20.0 m/s.
a) How far has it traveled after 4.0 seconds?
b) What is its velocity at that time?

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
