Question
Grant accelerates a 1kg ball 5.0m/s2 horizontally. The vertical acceleration of the ball is zero. The force of gravity is the only external force acting on the ball other than the forces Grant exerts on it.
a-How large is the horizontal force grant exerts on the ball at this instant to cause its 5.0m/s2 horizontal acceleration?
b-How large is the vertical force Grant exerts on the ball at this instant?
a-How large is the horizontal force grant exerts on the ball at this instant to cause its 5.0m/s2 horizontal acceleration?
b-How large is the vertical force Grant exerts on the ball at this instant?

bobpursley answer is correct for the first one
but for b there is a vertical force of 9.81 because of the gravitational force
