The answer is the same as many workers needed
Explanation:
1) the diagonal force times the sine of the angle it makes will give you the vertical component or y component . use this to get the vertical components of all the diagonal forces . add all the vertical components as well as the vertical forces together
2) the diagonal force times the cosine of the angle it makes gives the horizontal component or x component. do this to get the x component of all the diagonal forces.
add all the x components as well as the horizontal forces together to get the final x component
3)using the triangle of vectors, the resultant force is calculated
sum of y component = 3.2N
sum of x component= 5.7N
resultant force = 6.5N
Answer:
The acceleration of the train is 5 m/s².
Explanation:
Acceleration is the change in velocity over a given time interval.
Therefore, acceleration is given as:

Where,
are initial and final velocities and
is the time interval.
Here, 
This gives,

Therefore, the acceleration of the train is 5 m/s².
