answer is (D) 120N
C. 648 n
648 N
The force required to accelerate a body is found using Newton's second law, which states that force (F) equals mass (m) multiplied by acceleration (a). In this case, the force required would be 18 kg x 36 m/s^2, which equals 648 Newtons.
Since you don't tell us anything about friction or any other forces in the body's environment, we have to assume that there aren't any, and answer the question for that case. Any force, no matter how small, will accelerate any body, no matter how big. The greater the force is, the greater the acceleration will be. To find out exactly what the acceleration is, simply divide the force by the mass.

Without a unit, "36" is not an acceleration. we'll assume you're talking aboutunits of "meters per second2".F = M A = (18) x (36) = 648 newtons = about 146 pounds (rounded)
F = m A = (18) (36) = 648 newtons
If it is placed at a point where the force of gravity is such that it would accelerate the body at 1 ms-2.
Whenever there is a resultant force acting on a body which is having some mass, then that body will accelerate (or) A body whose velocity is changing with respect to time and having some mass then the body will accelerate.
Acceleration is in the same direction as the applied force.
A unbalanced force causes a body to accelerate. (From Newton's second law)
Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
