Answer:
Deceleration of 0.075m/s²
Explanation:
Given parameters:
Initial velocity = 5m/s
Time = 40s
Final velocity = 2m/s
Unknown:
The jogger's acceleration = ?
Solution:
To solve this problem, we use;
a =
a is the acceleration
v is the final velocity
u is the initial velocity
t is the time taken
a = = - 0.075m/s²
