Find the final speed of the train assuming no
friction.
Answer in units of m/s
no friction? How did it accelerate?
To find the final speed of the train assuming no friction, we'll need some additional information. Specifically, we'll need to know the initial speed of the train, any external forces acting on the train, and the time over which the train accelerates or decelerates. Once we have this information, we can use the equations of motion to calculate the final speed.
If the train is initially at rest (i.e., the initial speed is 0 m/s), and there are no external forces acting on the train, the final speed will also be 0 m/s. This is because if there are no forces acting on the train, it will not accelerate or decelerate, and will simply stay at rest.
If you have additional information, please provide it so that I can assist you further.
To find the final speed of the train assuming no friction, we need some additional information. Specifically, we need the initial speed of the train and any other relevant parameters such as the acceleration or time interval.
Once we have the necessary information, we can use the equations of motion to calculate the final speed of the train. The most commonly used equation is:
v_f = v_i + at
Where:
- v_f is the final velocity (speed) of the train,
- v_i is the initial velocity (speed) of the train,
- a is the acceleration, and
- t is the time interval of the motion.
Assuming no friction, we can consider the acceleration of the train to be zero. In this case, the equation simplifies to:
v_f = v_i
Therefore, the final speed of the train will be equal to the initial speed of the train when there is no friction.
