大家好,歡迎來到Yogi霸霸解題給你看,今天我要講解的是AP Physics C裡Rotation的作業。

A car starts from rest and moves around a circular track of radius 46.0 m. Its speed increases at the constant rate of 0.400 m/s2.

(a)What is the magnitude of its net linear acceleration 15.0 s later?

(b)What angle does this net acceleration vector make with the car’s velocity at this time?
