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.
