A train starting from rest moves with a uniform acceleration of 0.2 m s − 2 for 5 minutes. Calculate the speed acquired and the distance travelled in this time. Hint: In this problem, we are given with the acceleration of the train and the time taken by the train to cover some distance.
What is the velocity of a train starting from rest?
Assuming that the acceleration is uniform, find the acceleration and the distance travelled by the train for attaining this velocity.A. 2 m / s 2, 15 kmB. 3 m / s 2, 1 / 15 kmC. 1 / 15 m / s 2, 3 kmD. 4.5 m / s 2, 2 km A train starting from rest attains a velocity of 72 km / h in 5 minutes.
How do you find the acceleration of a train in 2 minutes?
A train starting from rest, attains a velocity of 20 m/s in 2 minutes.Assuming that that the accelerations uniform, find acceleration and distance travelled by the train in 2 minutes. Acceleration = v – u / t where v = final velocity, u = initial velocity and t = time taken.
What is the total distance moved when the train comes to rest?
From this velocity, brakes are applied and train comes to rest in 60 seconds. =>S=3600/2=1800m. So, total distance moved =900m+1800m=2700m.
What is the acceleration of a body during the first 10 seconds?
A body starts from rest and moves with a uniform acceleration of 10 ms −2 in the first 10 seconds. During the next 10 seconds, It moves with the maximum velocity attained. The total displacement of the body is

Complete step-by-step solution: We will assume that the train moves in a linear manner thus, the distance travelled will be equal to displacement and the speed of the train will equal to its velocity. The distance travelled during this time is 9000 m or 9 k m .
What is the distance travelled by the body during the motion?
Given here is a velocity-time graph of the motion of a body. What is the distance travelled by the body during the motion? Distance is given as speed times acceleration of the body. In a velocity-time graph, the distance travelled is calculated by determining the area of curve.
How do you calculate the time of a trip?
The time, or more precisely, the duration of the trip, can be calculated knowing the distance and the average speed using the formula: t = d / v. where d is the distance travelled, v is the speed (velocity) and t is the time, so you can read it as Time = Distance / Speed.
How long does it take a train to travel 500 miles?
Example: If a train can travel 500 miles with an average speed of 50 miles per hour, how long it would take it to complete a 500-mile route? The answer is 500 / 50 = 10 hours. The answer is 500 / 50 = 10 hours.
How do you find the distance between two points?
The formula for distance, if you know time (duration) and the average speed, is: d = v x t. where v is the velocity (average speed), t is the time and d is distance, so you can read it as Distance = Speed x Time.

The train starts from rest, and moves with uniform acceleration, so average velocity = . final velocity=10*2=20. Originally Answered: A train starts from rest. It moves through 1 km in 100 s with uniform acceleration. What will be its speed at the end of 100 s?
What is the average velocity of a train?
Homework Help: Average velocity of train. A train moving at an essentially constant speed of 60 miles/hr moves eastward for 40 min, then in a direction 45 degrees east of north for 20 min, and finally westward for 50 min.
What are the compound units most commonly used to indicate velocity?
The compound units most commonly used to indicate velocity include: Although average speed and average velocity are expressed in the same units, they are different concepts. Average speed considers distance, while average velocity considers displacement.
What is average velocity?
Updated: 09/27/2021 Average velocity is the change in the position of an object in a given direction, divided by the time it took for the object to move from the initial position to the final position. For example, an athlete who trains by running 5 miles north is likely to increase or decrease velocity at certain times during the run.
What is the average velocity of a bullet traveling 120 km?
So, the average velocity for the entire trip is the average velocity between t 1 and t 2, which we indicate with v 12. Thus, the average velocity of the bullet for the entire trip is 400 m/s. A car travels 120 km in 1.5 h (one and a half hour).

Therefore, the speed of the train during the given time after 5 minutes will be: 60 m s − 1 and the distance travelled during this time is 9000 m or 9 k m . Note: The train starts from rest and so the3 initial velocity of the train must be taken as zero.
