Hi, I got stuck on this and need help...
So, the given info are:
theta = 10 degrees
force, applied = -2.00 x 10^4 N
and mew k = 0.797
gravity = 9.81 m/s^2
Is that right? Now this is where I'm stuck.. I'm not sure what I need to find first and the equations to use to find it...
Please help... thank you!
The most massive car ever build was the official car of the General Secretary of the COmmunitst party in the former Soviet Union. Suppose this car is moving down a 10.0º slope when the driver suddenly applies the brakes. The net force acting on the car as it stops is -2.00 x 10^4 N. If the coefficient of kinetic friction between the car's tires and the pavement is 0.797, what is the car's mass? What is the magnitude of the normal force that the pavement exerts on the car?
