Explanation:
Given parameters:
Initial velocity = 8m/s
Final velocity = 2m/s
Time taken = 3seconds
Unknown and solution:
1. Is he accelerating or decelerating?
Tranh is obviously decelerating in this period. This is negative form of acceleration in which the speed reduces as the body comes to a stop.
Deceleration is a negative change in velocity with time i.e a body is reducing its velocity as time is changing.
2. What is the value?
Mathematically;
Deceleration =
Deceleration =
= -2m/s²
