It wont be accelerating at all, its in the process of stopping you ignorant sh it

What is the acceleration of vehicle moving with uniform velocity?
It has zero acceleration!!
What is the acceleration of a vehicle that changes its velocity from 80 km h to a dead stop in 13 s?
As velocity is reduced, acceleration is negative. Acceleration = change in velocity / time taken Velocity is m/second is got by multiplying 80 km p h by a fraction 5/18 which gives 200/9 m/s 200/9 is divided by 13s would give the required acceleration. That equals 1.7094 m/s2 So the retardation is 1.7094 m/s2
What is the acceleration of a vehicle that changes its velocity from 500 kmh to a dead stop in 20 s?
v=u+(a*t) 0=500+(a*20) (0-500)/20=a a=-25(km/h)/s
What is the rate at which an object changes velocity is called?
It is acceleration. Recall the accelerator hold in case of two wheeler and accelerator pedal in case of four wheeler. After the engine is started then we turn the throttle and vehicle starts moving from rest and soon the velocity goes on increasing. The more we turn in case of two wheeler and the more we press the pedal in case of four wheeler, the speed gets increased so quickly. So 'rate of' phrase is used to mean any change with respect to time or change happening in one second. Rate of displacement is velocity Rate of change in velocity is acceleration Rate of doing work is power Rate of flow of charge is electric current.
How does the velocity of a freely falling body change with time?
No. Velocity is speed (distance per unit of time) and in a given direction. Velocity has a vector associated with it. It has directionality. Any acceleration that changes the direction in which a body is moving will alter its velocity. A car going around a curve is experiencing lateral force and is moving sideways while moving forward. The net motion puts the vehicle through an arc. With no change of pressure on the accelerator pedal and no brake, the speed is constant, but the velocity of the car, the speed with (and) the direction vector of the car, will change. It may seem like a minor "technical" thing, but as the concepts are worked with, they become clear and "lock in" for easy application in the future. Speed if defined as the distance travelled divided by the time traveled. i.e If you walk 12 kilometer in three hours, your speed is 4 kilometers per hour.Acceleration is a change in speed. i.e 70kph to 80kph.Velocity not only tell us the speed but the direction also. i.e 125kph by NNE
When does one feel the effects of velocity in a moving vehicle when it is moving uniformly or when its motion changes?
One feels the changes in velocity, or acceleration, when the motion of the vehicle changes.

example of a change in acceleration while travelling at constant speed?
An example of a change in acceleration while traveling at constant speed can be observed when a vehicle moves in a circular path or takes a turn. Although the speed remains constant, the direction of the motion changes, which results in a change in velocity. Since acceleration is the rate of change of velocity, this alteration in direction causes a change in acceleration, even when the speed is constant.
What is the acceleration of a vehicle that changes its velocity from 500 kmh to a dead stop in 20 s?
v=u+(a*t) 0=500+(a*20) (0-500)/20=a a=-25(km/h)/s

What is the acceleration of a vehicle if it can achieve a speed of 70 ms in 35 seconds?
Acceleration = delta velocity/delta time a = 70 m/s/35 seconds = 2 m/s2 ------------
Is speed different from acceleration?
Acceleration is the change of velocity while Velocity is the rate of change of displacement (position).I-Edison of RSHS IX '10-'11
A car is moving at a constant speed is it accelerating?
This is one of those theoretical situations, like the frictionless surface you will see in physics problems. The short answer is that no, a car travelling at a constant speed is not accelerating. Acceleration is a change in velocity over time. Velocity is speed, so if you have zero change in velocity over a period of time, you have acceleration of zero. In the real world, you will have other factors acting on the vehicle, which would affect the acceleration.

How can a vehicle at the same time have a constant speed but changing velocity?
Speed is a scalar quantity (direction does not matter) and velocity is a vector quantity) ie velocity means speed in a specific direction. If you are changing direction (turning) in a car, your speed is the same, while your velocity changes.
