Answer:
Rotational inertia decreases proportional to the decrease in the radius of rotation.
Explanation:
10 joules of work is done by the object
Answer:
-1m/s
Explanation:
We can calculate the speed of block A after collision
According to collision theory:
MaVa+MbVb = MaVa+MbVb (after collision)
Substitute the given values
5(3)+10(0) = 5Va+10(2)
15+0 = 5Va + 20
5Va = 15-20
5Va = -5
Va = -5/5
Va = -1m/s
Hence the velocity of ball A after collision is -1m/s
Note that the velocity of block B is zero before collision since it is stationary
Because although they cannot see it, they can see it's influence on objects that can be seen, and it's effects.
