Answer:

<em>t = 1.02 s</em>

Explanation:

friction = 0 N (no slipping)

downward force along the inclined plane = F = mgsin(30.8)

                                                                        F = ma

⇒                                                                      a = 9.81 sin(30.8)

                                                                         a = 5.02 m/s^2

now we have

displacement = s = 2.6 m

acceleration   = a = 5.02m/s^2

initial velocity = Vi = 0m/s

time                 = t =  ?

<u>APPLYING THE 2ND EQUATION OF MOTION:</u>

<em>    S = (Vi)(t)+0.5at^2</em>

<em>2.6 = 0(t) + 0.5 * 5.02 * t^2</em>

<em>t = 1.02 s</em>

A vessel is filled with a liquid of density 1900 kg/m3 . There are two holes (one above the other) in the side of the vessel. Li
FromTheMoon [43]

Answer:

110 meters is the distance where they will intersect

Explanation:

given,

liquid density = 1900 kg/m³

distance of upper hole = 19 m

distance of lower hole = 117 m

acceleration due to gravity  = 9.8 m/s²

the speed at each point

v = \sqrt{2gh}  

for upper hole  v = \sqrt{2\times 9.8 \times 19}  

                         v  = 19.29 m/s

lower hole    v = \sqrt{2\times 9.8 \times 117}  

                          v = 47.88 m/s

The path for each is parabolic

x = v t

y = \dfrac{1}{2}gt^2  

y = \dfrac{1}{2}g(\dfrac{x}{v})^2  

y = \dfrac{gx^2}{2v^2}  

we get

upper hole

y = \dfrac{9.8\times x^2}{2\times 19.29^2}= 0.0132 x^2  lower hole

y= \dfrac{9.8\times x^2}{2\times 47.88^2}=0.00214x^2  y for upper hole = 80 + y for lower hole

0.0132 x^2= 98 + 0.00214 x^2

0.0082 x^2 = 98

x = 109.32 meters

110 meters is the distance where they will intersect

Describe two ways to change the frictional force between two solid surfaces.
Tanya [424]
<span>There are several ways to change the frictional force between two objects. The first one is to modify the surfaces of each object that will come in contact with each other. The smoother they get, the less friction there will be. But if the surfaces become rougher, more friction will be generated. If you don’t want to alter the surfaces, you can simply add lubrication to reduce friction.</span>

At the instant shown in the diagram, the car's centripetal acceleration is directed
serg [7]

Answer:

At the instant shown in the diagram, the car's centripetal acceleration is directed is discussed below in detail.

Explanation:

The direction of the centripetal acceleration is in a circular movement is forever towards the middle of the roundabout pathway. In the picture displayed, the East direction is approaching the center. So, the course of the car's centripetal acceleration is (H) toward the east.
