Given:
To be calculated:
Calculate the acceleration of given ball ?
Formula used:
Acceleration = change in velocity/Time taken
Solution:
Acceleration = change in velocity/time taken
Acceleration = v - u / t
★ Substituting the values in the above formula,we get
Acceleration = -4.4 - 6.0 / 0.04
= - 10.4 / 0.04
= - 1040 / 4
= -260 m/s²
Thus, the acceleration of given ball is -260 m/s².
We Know that :
(Always Initial velocity and final velocities are opposite in direction )
Now Put the Value in this Formula :
Therefore,
Acceleration of the Ball = 260 m/s² (Answer)
