What is the relative speed of two trains running in opposite directions?

What is the relative speed of two trains running in opposite directions?

When two bodies move in opposite direction, then the Relative Speed = Sum of Speeds i.e for e.g. for a person sitting in a train moving with a Speed of 40 km/hr in the west direction, another train which is going towards east with a Speed of 40 km/hr, will appear to move at a Speed of (40+40) = 80 km/hr.

What is the speed of a monkey of the train with a Trainr on the performance of 18 km/h 1 with SR trains on the peak of the train a velocity 12m H 10 S 15?

15 m s−1.

Does motion affect the rate of a clock as measured by an observer moving with it?

No, an observer moving in the same frame where the clock is measured, would observe the clock running normally. For example, an astronaut on a spaceship would observe the time in a clock in the spaceship is running with the same rate as it would if he was stationary on Earth.

When two objects are moving with same speed in the same direction what is the relative velocity of the two objects?

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.

At what time will the two trains meet?

The meeting point for the trains is given by −52.5x+409.5=48x, or 409.5=100.5x. This yields x=27367, or 4 hours and 4 minutes, and therefore the trains meet at 2.04 a.m.

How many seconds will a 500 meter long train?

How many seconds will a 500 metre long train take to cross a man walking with a speed of 3 km/hr in the direction of the moving train if the speed of the train is 63 km/hr? m/sec. = 30 sec.

What law is E mc2?

special relativity
One of the most famous equations in mathematics comes from special relativity. The equation — E = mc2 — means “energy equals mass times the speed of light squared.” It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing.

How does speed affect time?

According to special relativity, the faster an object moves relative to another object, the slower that first object experiences time. For GPS satellites with atomic clocks, this effect cuts 7 microseconds, or 7 millionths of a second, off each day, according to American Physical Society publication Physics Central.

What do we call a push or pull on an object?

A force is a push or pull that causes a change in speed, direction or shape. Newton’s third law says that for every action there is an equal and opposite reaction. This means that when one object pushes on another with a force, the other object pushes back on the first object with the same force.

How much time will a 500 m long train take to cross a tree if it is moving at a speed of 72 km h?

Answer: distance=500m=1/2 hours.

How is Superman able to move at super speed?

Superman, a Kryptonian, running at Super-Speed. Super Speed is the ability which grants Kryptonians and Daxamites, as well as other species, the ability to move, run, and fly a much greater speeds than a normal human. They are famously said to move ” Faster than a speeding bullet “, but most Kryptonians are able to move much faster than that.

Which is faster the Flash or the Superman?

Which is one of the main reasons why flash is seen as faster then superman in flat out travel speed. Superman’s powers follow Physics on a more “realistic” level then compared to the Flash’s “Speed Force” that protects the earth, everyone and everything the Flash passes from the Force of such speeds.

Is there a limit to how fast Superman can go?

Superman can go as fast as he wants to. He may not be able to get there faster than the Flashes, but he’ll still get there pretty quickly. Wherever there is. But there is no limit to Superman’s speed. Because once you go beyond light speed, then you’re breaking the rules of physics. And he can get there quicker when flying.

What was the speed of Superman in the Golden Age?

In the Golden Age comics, Superman couldn’t exceed 60 miles per hour, outrunning the fastest trains; however, as his career continued, his speed increased exponentially. This is presumably due to the continued effects of the Photonucleic Effect, that is, the effects of prolongued exposure to the Earth’s yellow sun on his body.
