Answer:
Mass and Gravity
Explanation:
Objects with mass exert forces on each other via the force of gravity. This force is proportional to the mass of the two interacting objects and is inversely proportional to the square of the distance between them.
The ans is A. 355 m/s as temperature is above stp
Given: Mass of Mars Mm = 6.24 x 10²³ Kg;
Mass of Phobos Mp = 9.2 x 10¹⁵ Kg
Gravitational Force F = 4.47 X 10¹⁵ N
Gravitational constant G = 6.67 X 10⁻¹¹ N m²/Kg²
Radius r = ?
Formula: F = GMmMp/r² derive r
r = √GMmMp/F
r = √(6.67 x 10⁻¹¹ N m²/Kg²)(6.24 x 10²³ Kg)(9.2 x 10¹⁵ Kg)/4.47 x 10¹⁵ N
r = √(6.67 x 10⁻¹¹ N m²/Kg²)5.74 x 10³⁹ Kg²/4.47 x 10¹⁵ N
r = √8.57 x 10¹³ m
r = 9,257,429 m
or r = 9.26 x 10⁶ m
(a) 3675 N
Assuming that the acceleration of the rocket is in the horizontal direction, we can use Newton's second law to solve this part:

where
is the horizontal component of the force
m is the mass of the passenger
is the horizontal component of the acceleration
Here we have
m = 75.0 kg

Substituting,

(b) 3748 N, 11.3 degrees above horizontal
In this part, we also have to take into account the forces acting along the vertical direction. In fact, the seat exerts a reaction force (R) which is equal in magnitude and opposite in direction to the weight of the passenger:

where we used
as acceleration of gravity.
So, this is the vertical component of the force exerted by the seat on the passenger:

and therefore the magnitude of the net force is

And the direction is given by

Answer:
umm section 2 and 4
Explanation:
because at section 2 it starts and at section 4 it moves again and stops at 3.
