If your speed changes from 10 kmh to 6 kmh you have a(n) acceleration. positive or negtive?

if your speed is in the positive direction you are slowing down and acceleration is the opposite direction and is negative acceleration.However if your speed is the negative direction ( like running backwards) and you slow down then acceleration is in the opposite direction and positive.In your case if speed is 10 kmh positive going to 6kmh then acceleration is negative


An object changes its speed from 10 m or s to 3 m or s is undergoing what acceleration?

Negative acceleration


What describes a trains acceleration if it changes speed from 25 m s to 10 m s in 240 s?

negative Acceleration


Compare the acceleration of a motorcycle that accelerates from 80 kmh to 90 kmh with the acceleration of a bicycle that accelerates from rest to 10 kmh in the same time?

Acceleration is the change in velocity divided by the time it takes to make that change;a= delta v/delta tAs you can see, the change in velocity for both vehicles is the same (10km/h), and the question states that they do it in the same amount of time. So the acceleration is the same;delta v1/delta t1 = delta v2/delta t2 = a.The fact that the motorcycle is already at a much higher speed is irrelevant.

A train approaching a crossing changes speed from 25 meters per second to 10 meters per second in 240 seconds how can the train's acceleration be described?

Acceleration = (change in speed) / (time for the change)= (10 - 25) / 240 = -15/240 = -0.0625 meter/sec2The acceleration is negative, which is a description of slowing down.


If a cars velocity changes from 0 ms to 30 ms 10 seconds later its average acceleration is?

Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2


How long does it take to travel 310 km at a speed of 100 kmh?

3 hours and 10 minutes!


What describes a train's acceleration if it changes speed from 25 ms to 10 ms in 240 s?

Since the direction of motion is not given, nor implied by speed, the acceleration can have any value between 0.146 ms-2 and 0.0625 ms-2.


If you jog for 1 hour and trevel 10km 10 kmh describes your?

if its km/h then it describes your speed in kilometers per hour


What is the acceleration of a car that maintains a constant velocity of 100 kmh for 10 s?

The car is travelling fast. However, its acceleation is zero because there is no change in velocity in 10 s.
