Solution
Solution:
C) Average acceleration during the 20 second interval,
from the graph,
Vf = 0 m/s
Vi = 5m/s
acceleration = change in velocity / time taken
=> a = 0-5/20
=> a = -0.25 m/s^2
D) the acceleration at 5 is given by the slope at 5 sec. ,
Let's find slope taking two points (0,5) and (5,0)
=> slope = acceleration = (5-0)/(0-5)
=> a = -1 m/s^2
