Best ResponseYou've already chosen the best response.0So this is what I did.. s=12m a=? t=1.75s 12=((1.75)^2a)/2 12=(3.0625a)/2 24=3.0625a a=7.84 netforce=55*7.84 netforce=431.2N

Best ResponseYou've already chosen the best response.1Net acceleration. a = 2*12/1.75² Net force ma = 5.5* 2*12/1.75² = 43.12 N

Best ResponseYou've already chosen the best response.0I get what your saying now. But the only problem is my choices are 120N, 54N, & 0N. But I can rule out 0N automatically
