A shopper pushes a 7.3 kg shopping cart up a 13° incline. Find the magnitude of the horizontal force, F, needed to give the cart an acceleration of 1.57 m/s2.
back when I used to artwork point crews, now and back we would would desire to roll out great carpets over the objective audience pit to soak up the somewhat some fluids that youngsters drip at stay shows, and we would circulate them in rolls on a 20' spike related to the front of a forklift. *A choir interior the history starts humming the conflict Hymn of the Republic* it extremely is relating to the time that i found out i'd would desire to be a billionaire when I grew up, and an eccentric one at that, so as that i ought to understand my destiny because of the fact the guy who makes Forklift Jousting a countrywide previous Time for the twenty first century. it extremely is time, u.s.. *Flag drops around the point*

Verified answer
F=ma
F=7.3*1.57
F= 11.461 N
cos 13 = .97437
F req = 11.762 N for acceleration
force of gravity to overcome=
sin 13 = .225
.225* 9.81*7.3= 16.109
*.97437=16.533
16.533+11.461 = 28N
This is very tricky as you need to remember that the pushing force is horizontal so must be broken up into an x and y component.

(7.3x1.57)/sin13 = answer
