The physics is involved in many daily activities,
Forrxample,
1. At the time of wake up when the alarm clock rings, the sound from the alarm clock is studied by using physics, the angular motion of the pins on the clock.
2. The oscillation and time period of the minute, second and hour hand.
3. The tranformation of our energy from food to the energy for motion of our body.
4. The balance of our house equipments on the tab
Answer:
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
