What is the resultant acceleration? A. The scalar that joins all the points along the path
B. The resultant displacement divided by time
C. The sum of all the acceleration vectors
D. The average of all the acceleration vectors

C.

The sum of all the acceleration vectors

Explanation: The word resultant means the sum of two or more vectors.

Since acceleration is a vector quantity,

The resultant acceleration will be the sum of all the acceleration vectors. Where there are two or more acceleration to be considered on an object in a system.
