Question

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

Answer 1

The acceleration: 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:

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