A three-picket fence (mass = 406 grams) on a glider is pulled by a constant force along a horizontal frictionless surface. The fence starts from rest 12.0 cm away from a photogate. Pickets and gaps are 2.0 cm wide each. Position is in centimeters and time is in seconds. Find the magnitude of the constant force in Newtons.
