Consider the following statements about the blocks shown in the diagram that are being pushed by a constant force on a frictionless table:

Correct answer: A. A only

  • A. A only
  • B. B only
  • C. Both A and B
  • D. Neither A nor B

Explanation

The following is the solution:By applying by a constant force on a frictionless table, all blocks move with the same acceleration. The net force on each block is different, as masses are different.F=ma, Since, F is constant, a will be constant as well.

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.
