I don't think so it would be some where between 9 and 10
Kinetic energy = 0.5 x m x v²
Kinetic energy = 0.5 x 3.8 x 2.2²
Kinetic energy = 9.196 J
The graph shows the production of Fe.
You can see from the graph that it increases rapidly and then slowly increases.
The answer is (A).
Cheers.
Explanation:
It is given that,
The angular acceleration of the basketball, 
Time taken, t = 3 seconds
We need to find the ball’s final angular velocity if the ball starts from rest. It can be calculated using definition of angular acceleration i.e.





So, the ball's final angular velocity is 30 rad/s. Hence, this is the required solution.
Consider that when heigt is 35 meters, the velocity is zero. The you can use the formula for free fall with initial velocity zero
Vf = √(2gh) = √(2*9.8m/s^2 * 35m) = √686m^2/s^2 = 26.2 m/s
Assumption: 35 m is the maximum height from the ground, else, if the maximum heigth from the ground is 35 m + 1 m = 36 m, the numbers are:
Vf = √(2*9.8m/s^2*36m) = 26.6 m/s
