The force of gravity is equal to the mass times centripetal acceleration.
Fg = m v^2 / r
The force of gravity is defined by Newton's law of universal gravitation as:
Fg = mMG / r^2
Therefore:
mMG / r^2 = m v^2 / r
MG / r = v^2
v increases as r decreases. So the planet with the smallest orbit (closest to the sun) will have the highest orbital velocity. Of the four options, that's Mercury.
The x-coordinates of the object at each time in a 1 ×1001 row vector named a11 using coordinate.
Coordinates are distances or angles, represented by numbers, that uniquely perceive factors on surfaces of dimensions (second) or in space of 3 dimensions.
Coordinates are hard and fast values that help to expose the exact position of a factor within the coordinated aircraft. A coordinate aircraft is a 2nd plane that's shaped by the intersection of perpendicular traces known as the x-axis and y-axis.

c) 
d) 
Explanation:
a) The initial vertical velocity is given by:

Where:
θ: 25°
v: is the magnitude of the speed = 23 m/s

b) The initial horizontal velocity can be calculated as follows:

c) The flight time can be calculated using the following equation:

Where:
x: is the total distance = 42 m

d) The maximum height is given by:
Where:
: is the final vertical velocity =0 (at the maximum heigth)
g: is the gravity = 9.81 m/s²
I hope it helps you!
D is the point where the planet moves the fastest. This is because it is in the perihelion, where the planet is moving at it’s fastest pace
