A mass of 10 kg moves with an acceleration of 10 ms-2, the force on it is
Correct answer: B. 100N
- A. 5N
- B. 100N
- C. 50N
- D. 25N
Explanation
To find the force exerted on the mass, use Newton's second law of motion: F = ma, where F is the force, m is the mass, and a is the acceleration. Here, the mass m is 10 kg and the acceleration a is 10 ms-2. Thus, the force F = 10 kg × 10 ms-2 = 100N. Therefore, the correct answer is 100N. Options 5N, 50N, and 25N result from incorrect calculations and do not satisfy the equation F = ma.

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.
