What is the force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second

The force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second is 12 newton.

Explanation:

According to Newton's second law based motion "the moving object's acceleration is based upon two terms - one is the total force acting upon that object and the other one is the net mass of the object."In mathematical term, F=ma. where F= force, m= mass, a= acceleration.So, by performing the calculation, 12N force will move the boy along with the wheel chair.

Yes yes yes very good
