Answer:

a) 4.0 s

b) 16 m/s

c) The distance covered between 4 - 5 s is four times the distance covered between 4 - 5 s

d) Equal distance are covered between 0 - 4 s and 4 -5 s

<em>Note: The question is incomplete. The complete question is as follows;</em>

<em>Refer to the chart below that has data about a moving object to answer the following questions. </em>

<em>Time Elapsed         0.0s   1.0s    2.0s    3.0s    4.0s    5.0 s </em>

<em>Distance Traveled 0.0m 10.0m 20.0m 30.0m 40.0m 80.0 m </em>

<em> a. What is the elapsed time between the 0-m mark and the 40-m mark?  </em>

<em>b. How large is the average velocity of the object for the interval from 0-5 s ?   </em>

<em>c. How does the interval of 3-4 s compare with the interval from 4-5 s in terms of distance?    </em>

<em> d. How does the interval of 0-4 s compare with the interval from 4-5 s in terms of distance?    </em>

Explanation:

a. From the data provide, time elapsed between the 0 m - 40 m mark is 4.0 s

b. Average velocity = total distance/ total time

average velocity = 80 m/ 5.0 s = 16.0 m/s

c. Distance covered between 3 - 4 s = 40 m - 30 m = 10 m

Distance covered between 4 - 5 s = 80 m - 40 m = 40 m

The distance covered between 4 - 5 s is four times the distance covered between 4 - 5 s

d. Distance covered between 0 - 4 s = 40 m - 0 m = 40 m

Distance covered between 4 - 5 s = 80 m - 40 m = 40 m

Equal distance are covered between 0 - 4 s and 4 -5 s

a 4357 kg roller coaster car starts from rest at the top of a 36.5 m high track. determine the speed of the car at the top of a
andrey2020 [161]
The correct answer is 17.24 m/s. You get the answer by subtracting the two heights of the tracks which are 36.5 and 10.8 m, and the answer is 25.7. Since you already know the height at which the kinetic energy will be coming from, you then divide the amount of weight the roller coaster has to the distance it needs to travel in order for you to determine the speed of the car. So that is, 4,357 kg and 25.7 m and the answer is 169 kg/m. Dividing it to the earth's gravity of 9.8 m/s you'll get 17.24 m/s.

3. A 75kg man sits at one end of a uniform seesaw pivoted at its center, and his 24kg son sits at the
bulgar [2K]

Answer:

The wife have to sit at 0.46 L from the middle point of the seesaw.

Explanation:

We need to make a sketch of the seesaw and the loads acting over it.

And by the studying of the Newton's law we can find the equation useful to find the distance of the mother sitting on the seesaw with respect to the center ot the pivot point.

A logical intuition will give us the idea that the mother will be on the side of her son to make the balance.

The maximum momentum with respect to the pivot point (0) will be:

M=75 *\frac{L}{2}

Where L/2 is the half of the distance of the seesaw

Therefore the other loads ( mom + son) must be create a momentum equal to the maximum momentum.

A 17 g audio compact disk has a diameter of 12 cm. The disk spins under a laser that reads encoded data. The first track to be r
sladkih [1.3K]

Answer:

0.00066518 Nm

Explanation:

v = Velocity = 1.2 m/s

r = Distance to head = 2.3 cm

\omega_f = Final angular velocity

\omega_i = Initial angular velocity = 0

\alpha = Angular acceleration

t = Time taken = 2.4 s

Angular speed is given by

\omega=\dfrac{v}{r}\\\Rightarrow \omega=\dfrac{1.2}{0.023}\\\Rightarrow \omega=52.17391\ rad/s

From equation of rotational motion

\omega_f=\omega_i+\alpha t\\\Rightarrow \alpha=\frac{\omega_f-\omega_i}{t}\\\Rightarrow \alpha=\frac{52.17391-0}{2.4}\\\Rightarrow \alpha=21.73912\ rad/s^2

Torque

\tau=I\alpha\\\Rightarrow \tau=\dfrac{1}{2}mR^2\alpha\\\Rightarrow \tau=\dfrac{1}{2}0.017\times 0.06^2\times 21.73912\\\Rightarrow \tau=0.00066518\ Nm

The torque of the motor is 0.00066518 Nm

A pole-vaulter is nearly motionless as he clears the bar, set 4.2 m above the ground. he then falls onto a thick pad. the top of
scZoUnD [109]
Refer to the diagram shown below.

Neglect wind resistance, and use g = 9.8 m/s².

The pole vaulter falls with an initial vertical velocity of u = 0.
If the velocity upon hitting the pad is v, then
v² = 2*(9.8 m/s²)*(4.2 m) = 82.32 (m/s)²
v = 9.037 m/s

The pole vaulter comes to res after the pad compresses by  50 cm (or 0.5 m).
If the average acceleration (actually deceleration) is (a m/s²), then
0 = (9.037 m/s)² + 2*(a m/s²)*(0.5 m)
a = - 82.32/(2*0.5) = - 82 m/s²

Answer: - 82 m/s² (or a deceleration of 82 m/s²)
