bagelkobi 13: kelly got number 10
bagelkobi 13: i used the normal axis so the x is parallel to the ground
y components: Fncostheta - muFnsintheta - mg = 0 x components: Fnsintheta + muFncostheta = m (F/(m+M)) and switch the sign of force of friction to find minimum
==Then Maureen helped clarify:==
frenchfri2389: i just used those equations
frenchfri2389: solved the first for Fn
frenchfri2389: then the second for F
Sckoodudey 2k: so is that F the min or the max
frenchfri2389: max
frenchfri2389: then reverse the signs for the muFn parts
frenchfri2389: and solve again to get min
Sckoodudey 2k: ok
Sckoodudey 2k: what was ur value for 10(a)(i)
Sckoodudey 2k: the first blank
frenchfri2389: 16.21
frenchfri2389: the Fmin
Sckoodudey 2k: o sry
Sckoodudey 2k: what was the Fmax
frenchfri2389: 62.05
Sckoodudey 2k: ok so mine are int he ballpark
