Acceleration, $a=-0.20\ m/s^2$

Explanation:

It is given that,

Initial speed of the explorers, u = 2.8 m/s

Finally it lands, v = 0

Maximum distance, x = 19.5 m

We need to find the gravitational acceleration on the surface of the exoplanet. Let a is the acceleration. It can be calculated using third equation of motion as :

v^2-u^2=2ax

$a=\dfrac{v^2-u^2}{2x}$

$a=\dfrac{(0-(2.8)^2}{2\times 19.5}$

$a=-0.20\ m/s^2$

So, the gravitational acceleration on the surface of the exoplanet is $0.20\ m/s^2$ . Minus sign shows that the acceleration is acting in downward direction. Hence, this is the required solution.

To solve for density the equation is density= mass/volume. To find mass you would need to change the equation to mass = density x volume.

An example according to socratic.org would be:

The density of copper is 8.933 g/cm3. What is the mass of a sample of copper with a volume of 10.00 cm3?

MassCu = 8.933g1cm3 x 10.00 cm3 = 89.33 g
