The forces exerted on an object are shown. (3 points)
Alex_Xolod [135]

Answer:

<em>F equals 3 N and the object remains stationary</em>. (second option in the list)

Explanation:

For sure to cancel acting forces, F must be 3N pointing up. But with regards to the object stationary or not, the question is tricky. We could have a ZERO net force applied, and the object moving at constant speed, which could still verify Newton's Laws. But considering the first answer option that refers to vertical motion upward where the object could be gaining potential energy, the most accurate response is that the force F has to be 3 N pointing up to make the object in equilibrium, and no motion in the vertical axis.

As soon as a bowling ball rolls off the edge of a table its horizontal component of velocity
IgorLugansk [536]

Answer:

B) Remains constant

Explanation:

The motion of the ball is the motion of a projectile, which consists of two separate motions:

- A horizontal motion with constant velocity, since there are no forces acting along the horizontal direction (if we neglect air resistance)

- A vertical motion with constant acceleration, due to the presence of the force of gravity (pointing downward), that accelerates the ball towards the ground with acceleration g=9.8 m/s^2.

We are only interested in the horizontal motion of the ball: we said that there are no forces acting along the horizontal direction, therefore the horizontal component of the the velocity of the ball is constant.
