A rabbit sees carrot to his right and starts jumping towards it with a velocity of 4.0meter per sec it speeds up to its maximum velocity of 13 meter per sec with a constant acceleration of 2.0 metre per sec square how long does it take for the rabbit to go from 4.0 metre per sec to 13.0 metre per square

    4.5 sec

    Explanation:

    Initial velocity u = 4 m/s

    Final velocity v = 13 m/s

    Acceleratiin a = 2 m/s^2

    Using v = u + at

    Where t is time

    13 = 4 + 2t

    13 - 4 = 2t

    9 = 2t

    t = 9/2 = 4.5 sec

    4.5 s

    Explanation:

    The initial velocity (u) = 4 m/s, the final velocity (v) = 13 m/s and the acceleration (a) = 2 m/s²

    To calculate the time it takes the rabbit to go from 4.0 m/s to 13.0 m/s, we use the formula:

    v = u + at

    Substituting values to get:

    13 = 4 + 2t

    Subtracting 4 from both sides:

    13 - 4 = 4 + 2t - 4

    9 = 2t

    Therefore, 2t = 9

    Dividing through by 2

    2t / 2 = 9 / 2

    t = 4.5 s

    Therefore it takes the rabbit 4.5 seconds to go from 4.0 m/s to 13.0 m/s
