Explanation:
From the question we are told that
The mass of the each railroad car is
The magnitude of the increased speed of the first car is
The magnitude of the speed of the other cars is
Generally from the law of linear momentum conservation is mathematically represented as
[initial momentum before the push = momentum after the push ]
So
=>
Generally the change in potential energy in the actor is equivalent to the workdone by the actor which is equivalent to the change in kinetic energy of the other three cart, this can be mathematically represented as
=>
=>
The answer is A,B,C that apply. I believe this is the answer i hope this helps have a good day.
Answer:
Explanation:
Time = (distance) / (average speed)
Time = (4,700 km) / (790 km/hr) = 5.9494 hours (rounded)
= 5hrs 56min 58 sec (rounded)
(4,700 km) / (1.609344 km/mile) = 2,920 miles
Speed = (distance covered) / (time to cover the distance)
(2,929 miles) / 5.9494 hours) = 491 miles per hour
