I had this question already I still have my answer the answer is D is the correct answer.
Given,
Weight of a block on the Earth = 980 N
Acceleration due to gravity on Earth = 9.8 N/kg
To find,
Weight of the block on the moon.
Solution,
The moon has acceleration (1/6) times that on earth. Let m be the mass of the block on the moon.
We know that,
W = mg
As mass of an object remains the same everywhere. Weight of the block on Moon is :
W' = mg'
As g'=(g/6)
So,
So, the weight of the block on the moon is 163.33 N.
Answer:
The arrow was moving at 16.2 m/s
Explanation:
The law of conservation of energy says that the kinetic energy of the arrow must be converted into the potential energy of the block and arrow after it they join:
where is the mass of the arrow, is the mass of the block, of the change in height of the block after the collision, and is the velocity of the arrow before it hit the block.
Solving for the velocity v, we get:
The arrow was moving at 16.2 m/s
Answer:
Yes
Explanation:
if it's staying at 5mph and cruising at that speed it's constant speed
