Answer:
-13.7m/s
Explanation:
If the car has a mass of 1400kg with a speed of +13.7m/s -> hits [email protected] rest and bounces with an elastic collision:
fm = -fm
Therefore, the speed the car will possess will be at a negative state.
= -13.7m/s
The correct option is: Option (D) not turn at all.
Explanation:
As the bar magnet is at rest, there is no change in magnetic flux. It means the change in magnetic flux in the magnetic flux in the loop is zero. Hence the induced current in the loop is zero and the loop will never turn at all. Therefore, the correct option is (D).
