Answer:
The mass and gravity.
Explanation:
Depending on how much mass there is in an object, will determine how fast/slow and object moves. This is the same with gravity, if there is a larger slope, there will be more energy, and if there is less there will be less movement.
Answer:
The force needed will be greater to hold the object at rest.
Explanation:
For a better understanding let's take a look at the attached image.
In the image there is an example of this condition, we have an object of 3 kg-f mass, the first angle between the horizontal and the inclined plane is 35°. When we increase the angle to 45°. We can realize that we need to hold the object with a stronger force.
The calculation and the equations based on Newton's laws can be found in the attached image.
Answer:
Explanation:
Given data:
Height,
Time,
Let the initial velocity of the object be <em>u</em>.
From the kinematic equation,
(rounding to tenth place)
