The principles used to solve this problem are similar to those in Multiple-Concept Example 17. A 205-kg log is pulled up a ramp

by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 25.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.855, and the log has an acceleration of 0.647 m/s2. Find the tension in the rope.

Answer:2538.43 N

Explanation:

Given

Mass of Log=205 kg

Ramp angle $=25^{\circ}$

Coefficient of Friction=0.855

log acceleration $=0.647 m/s^2$

Let T be the Tension

$T-mgsin\theta -f_r=ma$

Here $f_r=frictional\ Force=\mu N=0.855mgcos\theta =1556.76 N$

$T=mgsin25+m\times 0.647+1556.76$

T=849.04+132.63+1556.76=2538.435 N

An object is thrown vertically and has a speed of 25 m/s when it reaches 1/4 of its maximum height above the ground (assume it s

Crazy boy [7]

Answer:

$v_{i} =28.86\frac{ft}{s}$

Explanation:

Conceptual analysis

We apply the kinematic formula for an object that moves vertically upwards:

$(v_{f} )^{2} =(v_{i} )^{2} -2*g*y$

Where:

$v_{f}$ : final speed in ft/s

$v_{i}$ : initial speed in ft/s

g: acceleration due to gravity in ft/s²

y: vertical position at any time in ft

Known data

For $v_{f} = 25\frac{ft}{s}$ , $y=\frac{1}{4} h$ ; where h is the maximum height

for y=h, $v_{f} =0$

Problem development

We replace $v_{f} = 25\frac{ft}{s}$ , $y=\frac{1}{4} h (ft)$ in the formula (1),

[ $25^{2} =(v_{i} )^{2} -2*g*\frac{h}{4}$ Equation (1)

in maximum height(h): $v_{f} =0$ , Then we replace in formula (1):

$0=(v_{i} )^{2} - 2*g*h$

$2*g*h=(v_{i} )^{2}$

$h=\frac{(v_{i})^{2} }{2g}$ Equation(2)

We replace (h) of Equation(2) in the Equation (1) :

$25^{2} =(v_{i} )^{2} -2g\frac{\frac{(v_{i})^{2} }{2g} }{4}$

$25^{2} =(v_{i} )^{2} -\frac{(v_{i})^{2} }{4}$

$25^{2} =\frac{3}{4} (v_{i} )^{2}$

$v_{i} =\sqrt{\frac{25^{2}*4 }{3} }$

$v_{i} =28.86\frac{ft}{s}$

An example of a land feature formed by river erosion is?

KatRina [158]

<span>There are various examples of land features formed by river erosion. One of them is Delta. A delta is formed when sediments are deposited in a place where a river flow into an ocean or lake and build up a land form. Thus, a river delta is a land form that occurs as a result of deposition of sediments carried by a river as the flow leaves its mouth and enter a slow moving or stagnant water.</span>

A water balloon is thrown horizontally at a speed of 2.00 m/s from the roof of a building that is 6.00 m above the ground. At th

Elis [28]

Answer:

<u>The water ballon that was thrown straight down at 2.00 m/s hits the ground first, 0.19 s before the other ballon.</u>

Explanation:

The motions of the two water ballons are ruled by the kinematic equations:

$y=y_0+V_0t-gt^2/2$

We are only interested in the vertical motion, so that equation is all what you need.

<u>1. Water ballon is thrown horizontally at sped 2.00 m/s.</u>

The time the ballon takes to hit the ground is independent of the horizontal speed.

Since 2.00 m/s is a horizontal speed, you take the initial vertical speed equal to 0.

Then:

$y=y_0+V_0t-gt^2/2\\ \\ 0=6.00m-9.8\frac{m}{s^2} t^2/2\\ \\ t=\sqrt{2\times6.00m/9.8\frac{m}{s^2}}\\\\ t=1.11s$

<u>2. Water ballon thrown straight down at 2.00 m/s</u>

Now the initial vertical speed is 2.00 m/s down. So, the equation is:

$0=6.00m-2.00\frac{m}{s}t-9.8\frac{m}{s^2}t^2/2\\ \\ 4.9t^2+2t-6=0\\ \\ t=0.92s$

To solve the equation you can use the quadratic formula.

$t=\frac{-2+/-\sqrt{2^2-4(4.9)(-6)} }{2(4.9)}\\ \\ t=-1.33\\ \\ t=0.92$

You get two times. One of the times is negative, thus it does not have physical meaning.

<u>3. Conclusion:</u>

The water ballon that was thrown straight down at 2.00 m/s hits the ground first by 1.11 s - 0.92s = 0.19 s.
