<u>Answer:</u> The speed of the dog is 8 ft/s

<u>Explanation:</u>

Speed is defined as the ratio of distance traveled to the time taken.

To calculate the distance traveled by boat, we use the equation:

$\text{Speed of the dog}=\frac{\text{Distance traveled}}{\text{Time taken}}$

We are given:

Distance traveled by dog = 40 ft

Time taken = 5 seconds

Putting values in above equation, we get:

$\text{Speed of the dog}=\frac{40ft}{5s}\\\\\text{Speed of the dog}=8ft/s$

Hence, the speed of the dog is 8 ft/s

If you throw a pebble into a pond, ripples

spread out from where it went in. These

ripples are waves travelling through the

water. The waves move with a transverse

motion.

You place a 55.0 kg box on a track that makes an angle of 28.0 degrees with the horizontal. The coefficient of static friction b

Radda [10]

Answer:

$\theta=34 \textdegree$

Explanation:

From the question we are told that:

Mass $m=55kg$

Angle $\theta =28.0$

Coefficient of static friction $\alpha =0.680$

Generally, the equation for Newtons second Law is mathematically given by

For

$\sum_y=0$

$N=mgcos \theta$

for

$\sum_x=0$

$F_{s}=mgsin\theta$

Where

$F_{s}=\alpha*N\\\\F_{s}=\alpha*m*gcos \theta$

$F_{s}=0.68*55*9.8*cos 28$

$F_{s}=323.62N$

Therefore

$\alpha mgcos \theta=mg sin \theta$

$\theta=tan^{-1}(0.68)$

$\theta=34 \textdegree$
