Answer:
tanΘ
Explanation:
Let gravitational acceleration be g. When the avalanche starts to occur, the gravity force that is parallel to the slope is the same as friction force.
Gravity force that is parallel to the slope can be written as:
G = mgsinΘ
The friction force is the product of normal force and coefficient:
where normal force N is the gravity in the direction perpendicular to the slope
As stated before, gravity force that is parallel to the slope is the same as friction force:
Answer: The horse is moving with a uniform acceleration
Explanation:
According to the described situation, we are dealing with a <u>constant acceleration</u> (also called <u>uniform acceleration</u>), since the horse's velocity is changingn by a constant rate.
Let's prove it:
Firstly we are told the horse follows a straight path. In addition we are given its velocity:
3 m/s, then 4 m/s and 5 m/s
Since acceleration is defined as the change of velocity in time we can calculate it:
This is the horse's constant acceleration
