Yes. If you are traveling eastward but slowing down, your acceleration would be westward.
Yes. In fact, the acceleration can be in any direction.
Yes. if it is slowing down it is decelerating, or accelerating backwards, or in the opposite direction
Yes but only if you are reversing!
Yes it can.
If it is braking while travelling eastward it is accelerating westward
Yes it can, and it's really easy. -- A stone tossed upward, before it peaks and starts falling, has upward velocity and downward acceleration. -- A car driving east and slowing for a stop-sign has eastward velocity and westward acceleration.
well as we know that velocity is a vector hence it has magnitude as well as direction. Let us assign sign conventions for direction of velocities in this example: Let eastward velocity be positive and westward be taken as negative. Initial Velocity:-20 Final Velocity:+5 CHange in velocity=Final velocity-Initial Valocity Change in Velocity=5-(-20)=25m/s So change in velocity will be 25m/s
There is no acceleration if the car is travelling at a steady 54,000 miles per hour.
Straight line at a constant speed = no acceleration
velocity is a vector quantity and also acceleration is a vector quantity. Suppose my automobile is travelling in north direction and I apply brakes to it then until the automobile stops it will move in north direction while the acceleration will act in south direction as brakes are applied.
the car could be traveling in a straight line and slowing down (negative acceleration), speeding up (positive acceleration) or maintaining constant speed (zero acceleration).
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
It's zero
If something is traveling at a "steady" speed, it can't be accelerating.
As long as the 30 minute are spent driving in a straight line, the acceleration is zero.
