The force which will accelerate a 10 Kg mass at 98 cm/sec2 on a smooth horizontal plane is
Correct answer: A. 9.8 N
- A. 9.8 N
- B. 98 N
- C. 980 N
- D. 70 N
Explanation
To find the force, we use the formula F = m * a, where F is the force, m is the mass, and a is the acceleration. Given that the mass (m) is 10 kg and the acceleration (a) is 98 cm/sec2, we first convert acceleration to meters per second squared: 98 cm/sec2 = 0.98 m/sec2. Therefore, F = 10 kg * 0.98 m/sec2 = 9.8 N. The correct answer is 9.8 N. Other options are incorrect due to either wrong conversion of units or incorrect multiplication.

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.
