    Question

    If the velocity-time graph of a particle is represented

    by y = mt + c, then the particle is moving with–
    A constant speed Correct Answer Incorrect Answer
    B constant velocity Correct Answer Incorrect Answer
    C constant acceleration Correct Answer Incorrect Answer
    D varying acceleration Correct Answer Incorrect Answer

    Solution

    In this case the given equation shows that that the velocity is linear with time and therefore the particle is moving with constant acceleration because for a particle to acquire constant acceleration the graph of the velocity time graph should be in linear with the time function.
