What is his average acceleration from 10 to 20 seconds?
Pro

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)]

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant
