(b) Calculate the horizontal retarding force on the mower

(c) Calculate the normal force exerted vertically upward on the mower by the ground.

(d) Calculate the force the person must exert on the lawn mower to accelerate it from rest to 1.0 m/s in 2.0 seconds (assuming the same retarding force).

So I've already solved for the horizontal force by using trig and it was 57.98N. I also found the normal force by adding weight and the vertical component of the force. Now I am trying to find the force the person must exert on the lawn mower to accelerate it with the variables given.

Is this involving kinematics what should I focus on for this step?
