- Homework Statement
- The mass of a tractor is 200kg. The braking force on the tractor is 6.0kN. Calculate the acceleration as the tractor slows down.
- Relevant Equations
- g=9.8N kg^1
So I use 2000kg and 6.0kN to get 3ms^2

Jeff97 said:Its 2000kg. a=F/m but 6 is in kN so you change it to N=6000 a=6000/2000=3ms^2
Except for the units of acceleration.Mister T said:Well, you rewrite 6 kN as 6000 N. You wouldn't write N=6000, but otherwise you have done it correctly.
m/s^2 is correct. The posts I see say ms^2, not m/s^2.Jeff97 said:m/s^2 is wrong?
The acceleration of a tractor can be calculated by dividing the change in velocity by the change in time. This can be represented by the formula a = (vf - vi)/t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
Acceleration is typically measured in meters per second squared (m/s²) in the metric system or feet per second squared (ft/s²) in the imperial system.
Yes, the acceleration of a tractor can be negative if it is slowing down. This indicates that the final velocity is less than the initial velocity and the tractor is decelerating.
Acceleration is the rate of change of velocity with respect to time. This means that an object's velocity increases or decreases at a certain rate over a given period of time to produce acceleration.
The acceleration of a tractor can be affected by its mass, applied force, and frictional forces from the ground. Other factors such as air resistance, incline of the terrain, and engine power can also impact the acceleration of a tractor.
