How do you calculate the relative speed of two objects moving in the same direction?
When two bodies move in the same direction then the Relative Speed = Difference of Speeds i.e for a person a sitting in a train moving with a speed of 60 km/hr in the west direction, another train which is going towards the west with a speed of 40 km/hr, will appear to move at a Speed of (60-40) = 20 km/hr.
How do you calculate the speed of two trains?
When two trains are going in the same direction, then their relative speed is the difference between the two speeds. When two trains are moving in the opposite direction, then their relative speed is the sum of the two speeds.
When two objects are in motion the relative velocity of an object?
Relative velocity is the time rate of change of relative position of one object with respect to another. If two objects are moving in same direction, the magnitude of relative velocity of one object with respect to another is equal to difference in magnitude of two velocities.
How do you calculate the speed of a train?
Speed of Train
- Length of the train = 150m. Speed of the train = 90 km/hr. = 90 × 5/18 m/sec.
- Length of the train = 340 m. Length of the tunnel = 160m. Therefore, length of the train + length of the tunnel = (340 + 160) m = 500m.
- Speed of the train = 90 km/hr. Speed of the train = 90 × 5/18 m/sec = 25 m/sec.
What is the speed of a train?
The average speed of express trains, range from 36 kilometres per hour (22 mph) to 113 kilometres per hour (70 mph). Of this, counting up and down trains separately, 23 trains have an average speed more than 80 km/h, whereas 72 trains have an average speed between 70 and 80 km/h.
How is the motion of two objects relative to each other described?
How is the motion of two objects relative to each other described? Relative Motion The motion of two objects in space is relative to some defined point of reference. How can an object’s momentum be calculated?
What is the relationship between speed and distance?
Distance is equal to speed × time. Time is equal Distance/Speed. Distance = Speed × Time Speed = Distance / Time Time = Distance / Speed.
What is the distance the second car will travel for 3 hours?
The distance the second car will travels for 3 hours is equal to miles. Since , the solution is correct. Answer. It will take 3 hours for the first car to catch the second one. First car will travel 210 miles, and the second car will travel 180 miles before the first car catches the second one.
Can two objects intersect at the same time?
We can say, generally speaking, both objects may intersect at time t presuming that an existing displacement exists between both objects and that they are moving in the same direction and that acceleration is neither the same, or they are moving in the opposite direction and towards one another.
How long does it take for two cars to pass each other?
Divide both sides of the equation by 130. You get . Thus, it will take 3 hours for two cars to pass each other. Now, check the solution. The distance that the first car will travel for 3 hours is equal to miles. The distance that the second car will travel for 3 hours is equal to miles. Since , the solution is correct.
