A 0.30 g fly moving at 1.5 m s−1 is trapped by a spider’s web. The fly comes to rest in a time of 0.40 s. Calculate the magnitude of:
a) the change in momentum of the fly
b) the average force exerted by the web on the fly.
thanks for any help!
also if anyone could take a look at another question i'm struggling on, i'd appreciate it, thanks! it's here http://www.thestudentroom.co.uk/show....php?t=3570695
