If the activity of the engine oil is 79 decays/s , how much mass was worn from the piston rings per hour of operation?

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

Ineed the answers for these promblems i have
