Answer:
The acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.
Explanation:
Let suppose that maximum height of the arc is so small in comparison with the radius of the Earth.
Since the ball is launched upwards, then the ball experiments a free-fall motion, that is, an uniform accelerated motion in which the element is accelerated by gravity. Then, the acceleration experimented by the motion remains constant at every instant and position.
Besides, the gravitational acceleration in the Earth and, in consequence, the acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.
Answer:
The correct answer is option a.
Explanation:
Conservation of momentum :

Where :
= masses of object collided
= initial velocity before collision
= final velocity after collision
We have :
Two equal-mass carts roll towards each other.

Initial velocity of 
Initial velocity of
(opposite direction)
Final velocity of
(same direction )
Final velocity of
(same direction)


v = 0.5 m/s
rg135
The speed of the carts after their collision is 0.5 m/s.
Answer: Option (B) is correct.
The first law of thermodynamics is an adaptation of the law of conservation of energy, this is thoroughly adapted for the systems(thermodynamics). Law of conservation of energy defines that the total energy of a confined system is stable; energy can be transferred or converted from one form to another, but it cannot be formed or destroyed.
A 1-newton mass on earth would be 1000 newtons on star Z.
Funny enough, stars like this exist~! They're called "Neutron Stars."
I solved it and got 374.2N so i would put 375N
sorry i didn’t get any of the ones on there, i probably made a mistake.
