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
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.
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.
It is impossible to determine acceleration simply from time and distance.
IF the object begins from rest, then it travels 1.5 x 10^8 meters. (rounded)
No. Acceleration is the change in velocity(speed) over a period time.=====================================Another contributor bristled:Sorry. Velocity and speed are not two different words for the same thing.Velocity means speed and direction, and acceleration means any change in velocity.If the speed is constant but the direction is changing ... like turning a corner or drivingon a circular track ... then velocity is changing, and there is acceleration.

2.0 m/s^2
distance = 1/2 acceleration x time squared; acceleration is 7 m/s/s
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 kin of acceleration travels at a consent speed in a circular motion
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.
The acceleration is zero in this case.
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.
