Calculate the acceleration of a 2000-kg.

Paraphin [41]

Answer:

$0.25m/s^{2}$

Explanation:

In this problem we use Newton's Second Law formula:

$A= \frac{F}{M}$

F is for the force being applied, in this situation. The 500N is being thrust ed by the engine.

Substitute the force and mass:

$A = \frac{500 N}{2000} ms^{2}$

$A = \frac{1}{4} ms^{2}$

$A = 0.25m/s^2$

sergejj [24]

Answer:

The answer is "-72 k".

Explanation:

Please find the complete question in the attached file.

Given point:

$A=(0,0,0)\\B=(0,8,0)\\C=(9,8,0)\\D=(9,0,0)$

$\bar{AB} = (0i+8j+0k)-(0i+0j+0k)= 8j\\\\\bar{AC} = (9i+8j+0k)-(0i+0j+0k)= 9i+8j\\\\$

Calculating the area:

$Area=\left|\begin{array}{ccc}i&j&k\\0&8&0\\9&8&0\end{array}\right|$

$=i[8(0)-8(0)]-j[(0-0)]+k[(0-9(8))]\\\\=i[0-0]-j[(0)]+k[(0-72)]\\\\=i[0]-j[(0)]+k[(-72)]\\\\=-72 \ k$

A force of 16.88 n is applied tangentially to a wheel of radius 0.340 m and causes an angular acceleration of 1.20 rad/s2. What

telo118 [61]

Answer:

4.78 kg/m^2.

Explanation:

τ = Iα

Where,

τ = torque, around a defined axis (N∙m)

I = moment of inertia (kg∙m2)

α = angular acceleration

= 1.2 rad/s^2

τ = F * r

= 16.88 * 0.34

= 5.74 N.m

Therefore, I = 5.74/1.2

= 4.78 kg/m2
