Car is pulling a 3198kg trailer producing a accerlation of 0.2m/s2. Frictional force on the wheels is 740n. What is the applied force on the trailer?

  • Physics - ,

    The force required to produce the acceleration is given by Newton's second law F=ma.
    If
    m is mass in kg,
    a is acceleration in m/s²
    then force F is in newtons.

    To this force must be addded the frictional force 740 N to overcome friction.


    Note: the force unit newton is written in lower case when written in full, and with a capital letter N when abbreviated. This is true for other proper name units, such as Ampere, Pascal, etc.
