Answer:
-1.25m/s²
Explanation:
Given parameters:
Mass of object = 30kg
Initial velocity = 15m/s
Final velocity = 5m/s
Time = 8s
Unknown:
Acceleration of the object = ?
Solution:
Acceleration is the rate of change of velocity with time.
Acceleration = [tex]\frac{V - U}{t}[/tex]
V is the final velocity
U is the initial velocity
t is the time taken
To solve this problem, insert the parameters:
Acceleration = [tex]\frac{5- 15}{8}[/tex] = -1.25m/s²
This shows that the object is decelerating.
