By definition,
Momentum = Mass * Velocity
Let v = the velocity of the truck, m/s
The mass of the truck is 36,287 kg.
The momentum is 907,175 (kg-m)/s.
Therefore
907,175 (kg-m)/s = (36287 kg)*(v m/s)
v = 907175/36287 = 25 m/s
Answer: 25 m/s
Answer:
The lightbulb will not turn on because a switch is connected to it in parallel and when it is closed, like it is now, it becomes a short, by-passing the bulb completely.
