Question

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

    Answer:

    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

    Answer:

    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
