Slide 20 - Quiz

Open questions (5 x)

Slide 21 - Slide


Mention a couple of factors
which are of influence on the airfriction

Slide 22 - Open question

Tim approaches a red traffic light. He has his girlfriend on the back of his motorbike. He hits the brakes at the same distance from the lights
with the same force as he normally does.

Is this wise?  Can you explain what will happen and why?

Slide 23 - Open question

While hitting the gas pedal, the motor exerts a force of 5000 N on the car (m = 1550 kg). Since the total amount of frictional forces at the same time are no more than 2400 N, the car will start to accelerate.


Calculate this acceleration

Slide 24 - Open question


A boeing 747 is 
making a trip. 
Calculate the distance (in km) travelled
during the first 40 minutes

Upload a photocopy of your calculation

Slide 25 - Open question


You are driving with a speed of 34 km/h. Suddenly you see little ducks in the middle of the road at a distance of 30 meters. You need 1,8 seconds to react and after hitting the brakes, your car stands still within 2 seconds.
But will you be in time to save them?
MAke a calculation and a graph of this motion + Upload a photo
