As we know that the golfer hits the ball with a speed of 40 m/s at an angle of 50 degrees
so here we will have the range of the ball on the ground given as
R = v² sin2∅/g
so we will have
[tex]R =\frac{40^{2}sin(2*50) }{9.81}[/tex]
R = 160.6
So it will land at a distance of 160.6 m
so the distance from the hole is given as:
d = 160 -160.6
d = -0.6
To calculate the horizontal distance as the projectile travels Multiply the vertical height h by 2 and divide by the acceleration due to gravity g. Take the square root of the result from step 1 and multiply it by the initial projection velocity u to get the horizontal distance.
The maximum horizontal distance a baseball travels is the horizontal distance a baseball travels when returning to its initial height. An example of horizontal distance is the distance from an observer to a building, and an example of vertical distance is the height of a building. Players are given a reasonable amount of time to reach the hole and must wait an additional 10 seconds for the ball to fall into the hole. If the ball falls into the hole during this waiting time.

You should turn left and must yield to oncoming vehicles going straight.
Left turns must give way to oncoming traffic. A four-way stop allows the first driver to reach the intersection ahead of the other drivers after coming to a complete stop. Drivers entering the driveway from a driveway alley or curb must yield to vehicles already on the main road.
Gradually decelerate while looking in the rearview mirror. Transfer to the left lane. Watch out for oncoming vehicles and pedestrians. A green light means GO but you must let any remaining vehicles bicycles, or pedestrians at the intersection pass before you can proceed.

A Satellite revolves around the plant at altitude equal to R , radius of planet . The relationship between new gravitational force (f₄) and gravitational force f₀ is f₄ = 4 f₀.
.
Gravity is the force that attracts any two objects that have mass. Gravity is called gravitational force because it always tries to pull mass together and never push it away. In fact, every object, including you, is pulling on every other object throughout the universe! This is called Newton's law of universal gravitation. It is very noticeable in celestial bodies with huge masses such as the Sun, Earth, and Moon. This is because the force is proportional to the mass of the object. It is responsible for the movement of the planets around the sun and the moon around the earth. People also exert forces on each other, but due to their relatively small mass this is not very important . It is noted by G and mathematically ,
Gravitational force= Gm₁×m₂ /d²
where m₁ and m₂ are masses of two objects and d ----> distance between the centres of two objects and G is gravitational constant.
In question we one body is planet and other will be satellite.
Let us consider
M ----> Mass of plant
m------> mass of satellite
R ---> radius of planet
In first case, when satelite at a distance say altitude is equal to radius of planet (R) and the distance between the centres of two masses is 2R. Gravitational force between them is
(f₀ ) = GMm / (2R)²= GMm/ 4R² ---(1)
where, G---> gravitational constant
In second case, the satalite is on surface of a planet and distance between two masses is R.
New gravitational force between two bodies is
f₄ = GMm/ R²-----(2)
comparing (1) and (2) we get,
f₀ = f₄/4 => f₄ = f₀
Hence, the relationship between new gravitational force (f₄) and and gravitational force (f₀) is f₄= 4f₀.
