An astronaut with a mass of 80.70 kg is standing still on the surface of the Mars (Mars has an acceleration due to gravity of 3.
mariarad [96]

Answer:

Force, F = 68.93 pounds

Step-by-step explanation:

Given that,

Mass of the astronaut, m = 80.70 kg

Acceleration due to gravity on Mars, a=3.8\ m/s^2

The force acting on him is given by using second law of motion as :

F=m\times a

F=80.70\ kg\times 3.8\ m/s^2

F = 306.66 N

Since, 1 newton = 0.224 pound

F = 306.66 N = 68.93 pounds

So, 68.93 pounds force she exerts on the martian surface. Hence, this is the required solution.

3x4²-(-6)²+4-6x4 <br>Need help!! Please!!
goblinko [34]
Assuming the x stands for multiplication... follow the ordering rules:

First let's take care of the exponents. 4²=16 and (-6)²=36. At the same time I will add some spacing between the terms:

3x16 - 36 + 4 - 6x4

Now do the multiplications:

48 - 36 + 4 - 24

The rest is just addition and subtraction

48 - 36 + 4 - 24 = -8
