First you need to find the two different speeds of the car which is the distance/time. We find that the car first travels at an average of 6ms-1 and then after accelerating has a speed of 10ms-1. Acceleration is the rate of change of velocity over time, our change of velocity being 10-6=4ms-1 and the change in time being stated as 3 seconds we can convert this into...

(4/3)ms-2

What is the rate acceleration of a car that travels 70 miles per hour?

Zero acceleration if it is traveling in a straight line. An object that is accelerating must either be changing its rate of speed or its direction.


What is the acceleration of a car that travels in a straight line at a constant speed of 80 km per hour?

if the velocity is constant, the acceleration is zero. The acceleration is the rate at which the velocity changes, so if it stays the same, the car isn't accelerating.


If a drag racer travels 3 tenths of a mile in 8 seconds what is the rate of acceleration?

It is impossible to determine acceleration simply from time and distance.


How far will an object travel in 5528 seconds if accelerating at 9.81 ms2?

IF the object begins from rest, then it travels 1.5 x 10^8 meters. (rounded)


If a car starts from rest and travels a distance of 100 meters in 10 seconds what is the car acceleration?

2.0 m/s^2


What is the acceleration of a body which starts from rest and travels 87.5 m in 5 seconds?

distance = 1/2 acceleration x time squared; acceleration is 7 m/s/s


A horse is moving a constant speed of 8ms is the horse accelerating?

A constant speed means that the horse is neither accelerating nor decelearating Speed is a scalar which means it has a magnitude but no direction, while acceleration is a vector so it has both a magnitude and a direction. As the magnitude of the speed remains constant, the speed is constant but since the direction the horse travels in changes that horse is in fact accelerating.

What is the acceleration and magnitude of 32.5 kg object that travels 100m in 10 seconds?

You can't calculate the acceleration from the information provided. The object may be traveling at constant velocity, in which case the acceleration is zero; or it may start slowly end end up faster, or vice versa, in which case the acceleration will be non-zero.


What is the acceleration of an object that travels in a straight line at a constant speed?

The acceleration is zero in this case.


How does acceleration affect displacement?

If a body travels at a constant speed it will travel a certain distance (doesn't matter how far for our purposes). If it's accelerating then its speed is constantly increasing and therefore it covers more distance over every increment of time that it would if it were moving at its initial speed. So, acceleration increases displacement.


What is the acceleration of a car that travels in a straight line at a constant speed of 110 km h?

The acceleration of an object that travels in a constant straight line velocity is zero.
