A 10.0-kg box starts at rest and slides 3.5 m down a ramp inclined at an angle of 10° with the horizontal. If there is no fricti
Alenkinab [10]

Answer:

v_f = 3.45 m/s

Explanation:

As we know that box was initially at rest

so here work done by all forces on the box = change in its kinetic energy

so we will have

mg sin\theta L = \frac{1}{2}mv_f^2 - \frac{1}{2}mv_i^2

now we have

m = 10 kg

\theta = 10^0

L = 3.5 m

so we will have

10(9.81)sin10 \times 3.5 = \frac{1}{2}(10)(v_f^2 - 0)

2(9.81) sin10 \times 3.5 = v_f^2

so final speed is given as

v_f = 3.45 m/s

a large bottle contains a number of medicinal tablets each having a mass of 250mg the mass of all the tablets is 0.5kg calculate
lys-0071 [83]

Considering the change of units and rule of three, the number of tablets in the bottle is 2,000.

First of all, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 0.5 kg. You can see that the measurements are in different units of measurement, so you must make a change of units so that they are in the same units.

So, knowing that 1 kg is equal to 1,000,000 mg, you can apply the following rule of three: if 1 kg is equal to 1,000,000 mg, 0.5 kg is equal to how many mg?

1 kg ⇒ 1,000,000 mg

0.5 kg ⇒ x mg

So: x=\frac{0.5 kgx1,000,000 mg}{1 kg}

<u><em>x= 500,000 mg</em></u>

Then, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 500,000 mg. Now that the values ​​are in the same units, to calculate the number of medicinal tablets you must apply the following rule of three: if 1 tablet has a mass of 250 mg, how many tablets have a mass of 500,000 mg?

number of medicinal tablets=\frac{500,000 mgx1 tablet}{250 mg}

<u><em>number of medicinal tablets= 2,000</em></u>

Finally, the number of tablets in the bottle is 2,000.

You place a box weighing 268.3 N on an inclined plane that makes a 42◦ angle with the horizontal.
vivado [14]

Answer:

Wy = - 268.3*cos(42) = - 199.38 [N]

Wx = 268.3*sin(42) = 179.52 [N]

Explanation:

To solve this problem we must make a free body diagram, in the attached image we can see a free body diagram.

Taking the inclined X & y axes with the same angle of 42°, we can see that the weight can be decomposed on both axes.

Since the angle is adjacent to the y-axis, we can use the cosine function

Wy = - 268.3*cos(42) = - 199.38 [N]

Wx = 268.3*sin(42) = 179.52 [N]
