Question

For a particle moving along a straight line, acceleration is constant and is 4 ms 2. If the initial velocity of the particle is

8 ms1 then at what time will be the speed of the particle be 4ms1? ​

Answer 1

Answer:

There is a tendency to believe that if an object is moving at constant speed then it has no acceleration. This is indeed true in the case of an object moving along a straight line path. On the other hand, a particle moving on a curved path is accelerating whether the speed is changing or not.straight line is a curve with constant slope. Since slope is acceleration on a velocity-time graph, each of the objects represented on this graph is moving with a constant acceleration.line is horizontal, which indicates that the acceleration is constant. These two graphs show the main features of constant acceleration: constantly increasing or decreasing speed from the first graph and a horizontal line in the second graph of acceleration versus time.
