[QUOTE="discosucks, post: 4965908, member: 537022"] [h2]Homework Statement [/h2] An 850 kg car accelerates uniformly from rest to 33 m/s in a distance of 120 m. What is the magnitude of the net force acting on the car? [h2]Homework Equations[/h2] F = ma dynamic equations [h2]The Attempt at a Solution[/h2] [B]So i think i have this one sorted but just posting to see iv got it right . Seeing as i need acceleration to find the force i have to find it using the info i have so a= ? s= 120 v = 33 u = 0 t = not needed . v^2=u^2+2as (33)^2 = 0 + 2(a)120 1089 = 240a 4.5375 = a 4.5375 m/s^2 F = ma 850 x [B]4.5375 3856.875 N [/B] [/B] [/QUOTE]
