    This cab be solve using Newtons second law of motion:

    F = ma

    Where F is the force applied

    A is the accelaration = v/s

    V is the velosity

    S is the time

    M is the mass

    F = (2100 kg) * (96km/hr) (1000m / 1km) (1 hr/3600 s) / 3.5 s

    F = 16000 N is the force applied
