Given the force diagram of the basketball, what can you tell about the basketball motion?
VARVARA [1.3K]

Newton's laws allow to find the result for the movement of the basketballl:

  • On the vertical axis the ball is on the ground.
  • On the horizontal axis the ball is accelerating in the direction of the pushing force.

Newton's laws establish the relationship between the forces on objects:

  • The 1st law states that if the net force is zero the object is stationary or with constant speed.
  • The 2nd law gives a relation of the force with the mass and the acceleration of the body.
  • The 3rd. Law states that the force appears in pairs, one on each body with the same magnitude, but in the opposite direction.

Let's apply these principles to the ball's motion diagram.

The two vertical forces are in the opposite direction, one is due to the weight of the body and the other is the attraction of the earth to the support of the ball, they are of equal magnitude, not their action-reaction force and reluctant because it is applied to the same body

       In conclusion we can say that the ball is on the ground.

The two horizontal forces are in the opposite direction, the thrust force is greater than the friction therefore using Newton's second law the ball must be accelerating in the direction of the thrust force.

       In conclusion we can say that the ball is accelerating in the direction of the pushing force.

In conclusion using Newton's laws we can find the result for the motion of the basketball:

  • On the vertical axis the ball is on the ground.
  • On the horizontal axis the ball is accelerating in the direction of the pushing force.

Block A, with a mass of 4 kg, is moving with a speed of 2 m/s while Block B, with a mass of 8.4 kg, is moving in the opposite di
dybincka [34]

Answer:

The center of mass move with the velocity of -3.487 m/s.

Explanation:

Given values of block A.

Mass of block A, (M1) = 4 kg

Speed of block A, (V1) = 2 m/s

Given values of block B.

 Mass of block B, (M2) = 8.4 kg

Speed of block B, (V2) = -6.1 m/s

Below is the formula to find the velocity of center of mass.

Velocity = \frac{M1V1 + M2V2}{M1 + M2} \\

= \frac{4 \times 2 + 8.4 \times (-6.1) }{4 + 8.4} \\

= \frac{- 43.24}{12.4}\\

= - 3.487 m/s

Which of these statements is true? controlled data produces valid experiments. controlled experiments produce valid data. valid
Brums [2.3K]

Each of the choices may be considered right depending on the use of context or on how terms are defined, but the one that is most correct is:

 

"Controlled experiments produce valid data"

 

Controlled experiments are experiments in which factors which are not the interest of the study or which are not being studied are controlled or accounted for in the design, so that resulting data are less likely to be caused by some anomaly or by some variable other than those being studied. In usual research scenarios it is not the data itself that is acted upon in the <span>experiment - it is the experiment itself, the factors and the physical processes that will eventually yield data.</span>
