A force of 5 newton acts on a body of weight 9.8 Newton. What is the acceleration produced in ms-2?
Correct answer: D. 5.00ms-2
- A. 0.51ms-2
- B. 1.46ms-2
- C. 49.00ms-2
- D. 5.00ms-2
Explanation
To find the acceleration, we apply Newton's second law: F = ma, where F is the force applied, m is the mass, and a is the acceleration. The problem states that the force F is 5 Newtons. To find the mass, we use the weight W = mg, where g is the acceleration due to gravity (9.8 m/s2), and W is given as 9.8 Newtons. Solving for m gives us m = W/g = 9.8/9.8 = 1 kg. Substituting the values into F = ma gives 5 = 1 * a, solving for a gives a = 5 ms-2. The other options are incorrect due to miscalculations or misunderstandings of the relationships between force, mass, and acceleration as described by Newton's second law.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
