A shopper pushes a 7.3 kg shopping cart up a 13° incline, as shown in Figure 521. Find the horizontal force, F, needed to give the cart an acceleration of 1.63 m/s2.
ok, here is the formula to find horizontal force:
sum Fx= F1x +F2x = F1 + F2cos(theta), which also =mAx
if there are no forces given, how do i calculate F2cos(13degrees) and F2sin(13degrees)???
