Question

On object receives an impulse. Which of the following statements are true?

1) The impulse is a vector.
2) The impulse is equal to the change of the objects momentum.
3) The speed of the object must increase.
4) The kinetic energy of the object stays the same.
5) For the object to receive an impulse, a force must act on the object

Answer 1

The impulse is a vector quantity and equal to the change in momentum of the object. The speed of the object may or may not increase depending on the impulse. The kinetic energy of the object can change depending on the impulse and work done by external forces.

Step-by-step explanation:

The object receives an impulse, which is a vector quantity (Statement 1). The impulse is equal to the change in the object's momentum (Statement 2). The speed of the object may or may not increase, depending on the direction and magnitude of the impulse (Statement 3). The kinetic energy of the object can change depending on the impulse and any work done by external forces (Statement 4). To receive an impulse, a force must act on the object (Statement 5).
