Question

the force exerted on an object by earth's gravity is given by the formula F=9.8m, where F is the force in newtons and m is the mass of the object in kilograms.  newtons of gravitational force are exerted on a student with mass 52kg

Answer 1

If the student's mass is 52kg, then the force exerted by the earth's gravity is

F = 9.8m or 

 

F = 9.8 (52) = 509.6 Newtons
