I hope this helped :3
First you must calculate the speed of Amy and speed of Bill.
Now calculate the difference between Bill's speed and Amy's speed.
Amy's average speed is not faster. Bill's average speed is faster than Amy's by 6 m/sec.
Hope this helps.

Answer:
Faraday's law states that electromotive force induced is proportional to the rate of change in magnetic flux
Answer:
0.5 m/s
Explanation:
From Newton's Third law of motion,
Momentum of the cannon = momentum of the flatcar.
mv = MV........................ Equation 1
Where m = mass of the cannon, v = velocity of the cannon, M = mass of the flatcar, V = Velocity of the flat car.
make V the subject of the equation
V = mv/M................... Equation 2
Given: m = 10 kg, v = 50 m/s, M = 1000 kg
Substitute into equation 2
V = 10×50/1000
V = 500/1000
V = 0.5 m/s
Hence the speed of the flatcar = 0.5 m/s
