Given:
Initial velocity = 5 m/s
Final velocity = 2 m/s
Time = 30 seconds
Determine teh acceleration.
Formula for acceleration:
a = change in v/t
Solution:
Substitute the values of v and t to the formula for acceleration.
a = (2 m/s - 5 m/s)/30 seconds
a = -3 m/s / 30 seconds
a = -0.1 m/s^2
Final answer:
a = -0.1 m/s^2
