Answer : The total work done in raising the ball is, 0.98 J
Explanation : Given,
Mass of the ball = 0.075 kg
Height raised of the ball = 1.33 m
As we know that the object is moving with the constant velocity, that means the work done against the gravity will be the net-work done.
So, the work done will be:
where,
w = work done
m = mass of ball
h = height of ball
g = acceleration due of gravity =
Now put all the given values in the above formula, we get:
Thus, the total work done in raising the ball is, 0.98 J
