Given parameters:

Initial velocity of eraser = 5.0m/s

Time = 7.0s

Unknown:

Final velocity = ?

Solution:

Since we have been given the initial velocity and duration of the throw, we can apply the appropriate motion equation to solve this problem.

V = U - 2gt

where V is the final velocity

U is the initial velocity

g is the acceleration due to gravity = 9.8m/s²

t is the time taken

V = U - gt

V = 5 - (9.8)(7)

V = -63.6 or -64m/s

The velocity is -64m/s

An Object moving at a velocity of 30 m/s slows to a stop in 7 seconds. What was its acceleration

ollegr [7]

Answer:

<h3>The answer is 4.29 m/s²</h3>

Explanation:

The acceleration of an object given it's velocity and time taken acting on it can be found by using the formula

$acceleration = \frac{velocity}{time} \\$

From the question

velocity = 30 m/s

time = 7 s

We have

$acceleration = \frac{30}{7} \\ = 4.285714...$

We have the final answer as

A car increases its speed from 9.6 meters per second to 11.2 meters per second in 4.0 seconds. The average acceleration of the c

Gwar [14]

The acceleration is the change of speed/velocity over time. Thus to calculate this you do (V1-V2)/T or (11.2-9.6)/4 or 0.4 m/s^2

An LR circuit contains an ideal 60-V battery, a 42-H inductor having no resistance, a 24-ΩΩ resistor, and a switch S, all in ser

s2008m [1.1K]

Answer:

1.6 s

Explanation:

To find the time in which the potential difference of the inductor reaches 24V you use the following formula:

$V_L=V_oe^{-\frac{Rt}{L}}$

V_o: initial voltage = 60V

R: resistance = 24-Ω

L: inductance = 42H

V_L: final voltage = 24 V

You first use properties of the logarithms to get time t, next, replace the values of the parameter:

$\frac{V_L}{V_o}=e^{-\frac{Rt}{L}}\\\\ln(\frac{V_L}{V_o})=-\frac{Rt}{L}\\\\t=-\frac{L}{R}ln(\frac{V_L}{V_o})\\\\t=-\frac{42H}{24\Omega}ln(\frac{24V}{60V})=1.6s$

hence, after 1.6s the inductor will have a potential difference of 24V

flat block is pulled along a horizontal flat surface by a horizontal rope perpendicular to one of the sides. The block measures

Lelu [443]

Answer:

Answered

Explanation:

v= 1 m/s

A= 1 m^2

m= 100 kg

y= 1 mm

μ = ?

ζ= viscosity of SAE 20 crankcase oil of 15° C= 0.3075 N sec/m^2

forces acting on the block are

F_s ← ↓ →F_f

N= mg

F_s= shear force = ζAv/y F_f= friction force = μN

now in x- direction F_s= F_f

ζAv/y = μN

0.3075×1×1×1/1×10^{-3} = μ×100

⇒μ=0.313 (coefficient of sliding friction for the block)

Now, as the velocity is increased shear force also increases and due to this frictional force also increases.

Now, to compensate this frictional force friction coefficient must increase

as v∝μ

At the normal boiling temperature of iron, TB = 3330 K, the rate of change of the vapor pressure of liquid iron with temperature

Margaret [11]

The molar latent enthalpy of boiling of iron at 3330 K is ΔH = 342 $\times$ 10^3 J.

<u>Explanation:</u>

Molar enthalpy of fusion is the amount of energy needed to change one mole of a substance from the solid phase to the liquid phase at constant temperature and pressure.

d ln p = (ΔH / RT^2) dt

(1/p) dp = (ΔH / RT^2) dt

dp / dt = p (ΔH / RT^2) = 3.72 $\times$ 10^-3

(p) (ΔH) / (8.31) (3330)^2 = 3.72 $\times$ 10^-3

ΔH = 342 $\times$ 10^3 J.
