Slide 1 - Tekstslide

What are the steps in the problem solving procedure?

Slide 2 - Tekstslide

The formula of speed
a) What is the unit of speed?
b) What are the two physical quantities in this unit?
c) What do you have to do with these quantities to calculate speed?

d)  What is the formula of speed?

Slide 3 - Tekstslide

Now we are starting with the calculations



  • Apply the problem solving procedure.
  • You're always allowed to use a calculator.

Slide 4 - Tekstslide

What is the formula of the speed of sound?

Slide 5 - Tekstslide

What is the problem solving procedure?

Slide 6 - Tekstslide

Miss Mulder has setup an experiment to measure the speed of sound. Mister Brands stands 686 meters away from her and hits two wooden planks together to produce a loud sound. It takes 2 seconds before Miss Mulder hears the sound. According to the data of this experiment, what is the speed of sound? 


Slide 7 - Tekstslide

What is the speed of sound?
look it up to check wether your answer is correct.

Slide 8 - Tekstslide

In the distance you see a group of people playing volleyball. One player hits the ball, 1.5 seconds later you hear the sound of it. How far away from you are they playing volleyball?


Slide 9 - Tekstslide

Natasha sees a lightning flash, it takes 15 seconds before she hears the thunder of it. How far away did the lightning flash occour?

Slide 10 - Tekstslide

You clap your hands above a well. The well is 50 meter deep. How long does it take before you can hear the echo of the sound of your clap? Use the problem solving procedure.

Slide 11 - Tekstslide

7) A jet plane is 10000m above ground, flying at a speed of 250m/s. By the time the sound from the engines has reached you on the ground, how much further has the jet moved forward?

Slide 12 - Tekstslide

1) Runners in the 100-metre dash have complained that the runner nearest the gun has an unfair advantage.

a. What might this advantage be?
b. What time difference would there be between runners hearing the pistol?
c. Humans have a reaction time of 0.1s, would the difference be important enough to change where the starter sits?
