Explanation:
the velocity graph of a ball mass 20mg moving along a straight line
there were different outcomes each time.
The position of the mass is given by (in cm):

The velocity is the derivative of the position:

Substituting t=0.40 s, we can find the velocity at this time:
Answer:magnetic and electric fields
Explanation:
