Can someone please help me right now?

Dynamics Physics help urgent Homework Statement Sara wonders what the normal force on her 1.0 kg water bottle would be if she tries to lift it with 4.0 N (she used a Newton spring scale to measure her applied force). What is the bottle's acceleration? Homework Equations Fg = mg...

Sorry, I meant 12.427 m/s^2 backwards. I basically did: Fnet = Fa + Ff (sum of all the forces) ma = -Fa - Ff (1350)(a) = -9500-7276.50 a = -12.427 m/s^2 backwards

For sloving initial velocity, I will use Vf^2 = Vi^2 + 2ad

Fnet=ma If a is negative (backwards), then shouldn't Fnet also be negative.

Important info I forgot to mention: Applied braking force is 9500 N. I am not sure which way is the Fnet. I found Fg, which is 13230 N downwards. I found Ff which is 7276.50 backwards. I found acceleration which is 12.427 N backwards. However, my teacher told me to make the Fnet positive, but...

Dynamics physics urgent help please! Homework Statement A 1350 kg car narrowly avoids running off of a washed out bridge. The coefficient of friction between the car and the road is 0.55. If the skid marks are 100 meters long, what was the initial velocity of the car? Homework...
