A box slides down a frictionless plane inclined at an angle θ ¸ above the horizontal. The gravitational force on the box is dire
DedPeter [7]
<h2>Answer: at an angle \theta below the inclined plane. </h2>

If we draw the <u>Free Body Diagram</u> for this situation (figure attached), taking into account only the gravity force in this case, we will see the weight W of the block, which is directly proportional to the gravity acceleration g:  

W=m.g

This force is directed vertically at an angle \theta below the inclined plane, this means it has an X-component and a Y-component:

W=W_{X}+W_{Y}

W_{X}=m.g.cos(\theta)

W_{Y}=m.g.sin(\theta)

Therefore the correct option is c

I kinda don’t know how to solve this I need help.
NemiM [27]

Answer:

the answer is 11 N left

Explanation:

there is more force being applied in the direction left, so the ball will move left. to find the net force that the ball will move in that direction subtract the force being applied in the opposite direction. so, 16N-5N=11N. your answer in 11 N left.

A sports car is advertised to be able to stop in a distance of 50.0 m from a speed is 99.0km/h. What is its acceleration in m/s2
Shtirlitz [24]
99.0km/h =27.5m/s (this is the initial speed)
The final speed is zero
The distance is 50.0m
Therefore you use the formula:
vfinal²=vinitial²+2ad
a=(vfinal²-vinitial²)/2d
 = (0²-27.5²)/(2x50.0)
 =-7.5625 or in correct sigdigs -7.56m/s²
Hope this helps!
