the gravity force between Mars and an object near Earth's surface as much lower than the force between an object on Earth surfac

e of Earth if the speaking of a hammer when dropped increase from 0.0 m / s to 15.0 m / s and 4.04 seconds what is the acceleration due to the gravity force of the surface of Mars​

<u>The acceleration:</u> is defined as the change of the velocity in 1 second.

In symbols

a = \frac{V_{f}-V_{i}  }{t}

where:

  • V_{f} : the final velocity
  • V_{i} : the initial velocity
  • t : the time if the change

In our problem:

a = \frac{15-0 }{4.04}=3.713 m/s^2

Aleks [24]

Answer:

Yes

Explanation:

There was a force, 500 lb.

and a motion in the direction of the force, in this case a negative direction.

Therefore the lifter did negative work on the mass of the  barbell against gravity.

Gravity would do positive work against the mass of weight when the lifter lowers the barbell as the force vector and the motion vector are in the same direction.
