what did everyone get for the 3 5/6 msrks questions ?
I got 170-ish on the last one
for the slope one I set s =0 with sin40 t find the tine , and max height in hopes for atleast 2 marks -the phrasing of the question wss just weird, was confused
for the QWC. i wrote compression -> elastic strain energy
strain -> kinetic
Force by car against ground causes force by ground against car - Newtons 3rd law.
Resultant force - hence velocity
when spring returns to normal , stationary
other than those three , paper was fine imo
