Ok so today's paper then!
Here are my answers, feel free to check me and add any I miss!
•The rose petals olympics question;
Copper: because it is ductile and therefore can be beaten into shapes plus it is resistive to high Temps
Steel: because it is tough and therefore won't break under the stress of the weight.
•The spider question:
I used the weight of the spider plus the weight of the fly times gravity to find the acceleration.
•Car Spring Question:
I argued that a stiffer spring would be dangerous on a bumpy road causing it to bump and tumble which could lead to injury.
•Hammock Question:
I resolved the vectors and received a value of around 617N. Some people got 643 so I'm not sure!
•Tennis ball Question:
I measured the length of the image with my ruler and argued that since the ball falls the vertical distance in 1/20th of a second and because we know gravity to be 9.81 adding to that my measurement , we could calculate the distance the ball fell between X And Y.
•Rower Question:
I drew rectangles underneath the graph and then added them all up to give me an approximate value for the amount of work done.
•Viscosity Question:
I talked about plotting a graph of radius against flow rate and then using the gradient to confirm a value for the viscosity!
Well these Are the parts I remember! What about you?
