A mass of 100kg is acted on by a 400N force acting vertically upward and a 600N force acting at a 45 degrees angle.Calculate the

slava [35]

Answer:

A 1.56 see below

Explanation:

I will assume the 45 degree force is upward

vertical component = 600 sin 45 = 424.26 N

added to the other vertical force will total 824.26 N

F = ma

824.26 = 100 * a shows a = 8.24 m/s upward

Now we have to assume the mass is ALSO acted on by gravity and this value is given as 9.8 ( so downward is positive)

9.81 - 8.24 = 1.56 m/s^2

A disk initially rotated counterclockwise at 1.0 rad/s, but has a counterclockwise angular acceleration of 0.50 rad/s^2 for 2 se

Mumz [18]

Answer:

Initial angular position of the disc is 3 radian

Explanation:

As we know that the angular acceleration of the disc is given as

$\alpha = 0.50 rad/s^2$

initial angular speed is given as

$\omega = 1 rad/s$

now we know that angular displacement of the disc is given as

$\theta = \omega t + \frac{1}{2}\alpha t^2$

$\theta = 1(2) + \frac{1}{2}(0.5)(2^2)$

$\theta = 3 rad$

now we have

$\theta_f - \theta_i = 3 rad$

$6 rad - \theta_i = 3$

$\theta_i = 3 ard$

Conduction

sashaice [31]

conducted

Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them. This then continues and passes the energy from the hot end down to the colder end of the substance.

Find the mass of the car.

SpyIntel [72]

$\huge\boxed{770.8\overline{3}\ \text{kg}}$

We know that force equals mass times acceleration, so substitute in the known values and solve.

$\begin{aligned}F&=ma\\1850&=m*2.4\\1850\div2.4&=m*2.4\div2.4\\\boxed{770.8\overline{3}}&=m\end{aligned}$
