You are walking up an icy slope. suddenly your feet slip, and you start to slide backward. will you slide at a constant speed, o
r will you accelerate?
2 answers:
Answer:
Will accelerate with g.sinθ, where θ is the angle between the ground and the inclination of the slope.
Explanation:
When any mass is sliding down the inclined plane will be affected by the acceleration due to gravity and some component of this acceleration will act on the body.
Let θ be the angle of inclination of the inclined slope from the horizontal.
then from the attached figure we can clearly get the component of acceleration along the slope.

Answer:
<h2>0.67 m/s²</h2>Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as

Answer:
Explanation:
Let x be the distance to the shore
From trigonometry properties:
Answer:
Juan and Kuri complete one revolution in the same time, but Juan travels a shorter distance and has a lower speed.
Explanation:
Since Juan is closer to the center and Kuri is away from the center so we can say that Juan will move smaller distance in one complete revolution
As we know that the distance moved in one revolution is given as
also the time period of revolution for both will remain same as they move with the time period of carousel
Now we can say that the speed is given as
so Juan will have less tangential speed. so correct answer will be
Juan and Kuri complete one revolution in the same time, but Juan travels a shorter distance and has a lower speed.
