Question

I am having a hard time figuring out which formula to use inmy word problem I have in my physics book. I am in grade 112phyics, and am currently working in the dynamics Unit. Thanks forany advice you can give me on this question. :) A 15 kg object experiences an applied force of 5.5 N [N] andan opposing frictional force of 2.5 N [S]. If the object startsfrom rest, how far will it have travelled after 4.0 seconds? I am having a hard time figuring out which formula to use inmy word problem I have in my physics book.

Explanation / Answer

Net force = sum of all forces Fnet = 5.5N - 2.5N = 3N Fnet = ma 3N = 15kg *a a = 0.2m/s2 x = vot + 1/2at2 and initial speed was0m/s x = 1/2 * 0.2 * 42 x = 1.6m Hope that helps x = 1.6m Hope that helps
