heres what i have
b) Fnety= Fn-mg2cosθ
m1a= mg1sinθ-Usm1gcosθ-Fwall
m2a= mgsinθ-Usm2gcosθ
c) Fwall= mgsinθ-Usm1gcosθ
Fwall/m1g= (m1gsinθ-Usm1gcosθ)/m1g = Sinθ-Uscosθ
look good?
Urgent help with physics incline problem!
A block of mass m is on an inclined ramp. The coefficient of static friction between the block and the ramp is µs. There is also a wall on the ramp situated below the block (see diagram).
