Answer:
15.C Mucus reduces friction
Explanation:
Acceleration of an object is calculated by finding the change in its velocity divided by time taken.
If
is initial velocity,
is final velocity and t is time taken. Then the acceleration of the object is given by :
.....(1)
So, the above equation is used to find acceleration. It is called the first equation of motion. After rearranging equation (1), the correct options are :




Reference point is most often given a value of zero to describe an object's position on a straight line
