    Answer:

    Acceleration is 1.2 m/s^2.

    Explanation:

    initial velocity, u = 0

    distance, d = 60 m

    time, t = 10 s  

    Let the acceleration is a.

    use second equation of motion

    s= u t +0.5 at^2\\\\60 = 0 + 0.5 \times a \times 10\times 10\\\\a = 1.2 m/s^2

    Now according to the Newton’s second law

    Force = mass x acceleration

    Let the mass is m.

    F = m x 1.2 = 1.2 m Newton
