The acceleration would be 6m/sThis is because of the formula, "f/m=a" to find the acceleration; We would need to subtract the force of the friction which equals 1380, then divide that by the mass (which was 230) to get the answer 6
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
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.
Answer:

Explanation:
<em>Assuming that the thermal expansion of brass cube occurs isotropically (i.e. equal in all the directions).</em>
Given:
- length of the cube,

- change in temperature of the cube,

- coefficient of volume expansion,

<u>Hence volume of the cube:</u>

Now the volume of the cube after expansion:



Therefore,

<u>Now the percentage change in the edges of the cube:</u>
