Explanation / Answer
1) (A)First
The Newtons first law is law of intertia.
2)(C)An inertial
Such reference systems are called as inertial refrence sytem.
3)None of the options seems right
4)(B)equal to g
since it is travelleing with constant velcoity so its acceleration is zero. The net acc is g only.
