The question can be solved using the principle of Newton's second law of Motion. Newton's second law of motion  is often stated as F=ma, which means the force acting on an object is equal to the mass (m) of an object times its acceleration.

F=ma

According to the given data,

Force of 20N is applied to the object

acceleration of 5 m/s^2 is obtained on the object

From Newton's second law of motion,

F=ma

20N =m x 5

m=4kg

To obtain an acceleration of 1 m/s^2, the force required will be

F= ma

F= 4 X 1 = 4 N

To obtain an acceleration of 10 m/s^2, the force required will be

F=ma

F= 4 x 10

   = 40 N
