Question

E) 100 N es that a penguin Y 5 3. A penguin is sliding across a glacier with a constant, non-zero velocity. Which of the following statements about the penguin's motion is true? A) A non-constant force is being applied to the penguin B) A net force on the penguin is in the direction of the penguin's motion. The net force on the penguin is opposite the direction of the penguin's motion. D) The net force on the penguin is equal to zero. E) The frictional force on the penguin is equal to zero. Page 1 of 8

Explanation / Answer

Since the velocity of the penguin is constant, the acceleration will be zero and thus the Net Force on the penguin will be zero. Therefore, A,B and C are incorrect.

Since the velocity is maintained constant, a dissipative force must be acting to make the acceleration of the penguin zero. Hence it is wrong to say that the friction force is zero here and so statement E is also incorrect.

Statement D is the only correct statement.
