A train travels on a straight track passing signal A at 20m/s and reaches signal B 100m further than A.At B the velocity of the train in m/s is_______
Good
To find the velocity of the train at signal B, we need to determine the time it takes for the train to travel from signal A to signal B.
Let's use the following formula to calculate the time:
Time = Distance / Velocity
Given that the train passes signal A at a velocity of 20 m/s, the distance from A to B is 100 meters. Plugging these values into the formula:
Time = 100 meters / 20 m/s
Time = 5 seconds
Now, we can find the velocity of the train at signal B using the formula:
Velocity = Distance / Time
The distance from signal A to B is 100 meters. The time is 5 seconds. Plugging these values into the formula:
Velocity = 100 meters / 5 seconds
Velocity = 20 m/s
Therefore, the velocity of the train at signal B is 20 m/s.
To calculate the velocity of the train at signal B, we need to consider that the train travels 100 meters further from signal A to signal B. We know the speed of the train at signal A is 20 m/s.
Velocity is defined as the rate at which an object changes its position with respect to time. In this case, the train's velocity at signal B is the speed of the train plus the additional distance traveled.
Therefore, the velocity of the train at signal B can be calculated as follows:
Velocity at B = Velocity at A + Additional distance / Time
Given:
Velocity at A = 20 m/s
Additional distance = 100 m
Since we don't have information about the time it takes for the train to travel from A to B, we cannot accurately compute the velocity at B. The velocity would depend on the time taken to cover the additional 100 meters. If you provide the time taken or more information, we can assist you further in calculating the velocity at signal B.
