Answer:

A, C

Explanation:

In order for a box to be moving at constant velocity, that means acceleration must be 0(as the speed isn't increasing). Thus, since F = ma, and a is 0, the net force must also be 0. The diagram must be completely balanced in every direction, which is why the two horizontal arrows must be equal values.

C is also true because gravity is a stronger force here than the applied force. We can calculate the force due to gravity with Fgravity = mg. Thus, we get the force as a result of gravity = 9.8*50, which is around 500N and much larger than the applied force of 200N.

A large grinding wheel in the shape of a solid cylinder of radius 0.330 m is free to rotate on a frictionless, vertical axle. A

Flura [38]

Answer:

The mass of the wheel is 2159.045 kg

Explanation:

Given:

Radius $r = 0.330$

m

Force $F = 290$ N

Angular acceleration $\alpha = 0.814 \frac{rad}{s^{2} }$

From the formula of torque,

Γ $= I\alpha$ (1)

Γ $= rF$ (2)

$rF = I \alpha$

Find momentum of inertia $I$ from above equation,

$I = \frac{rF}{\alpha }$

$I = \frac{0.330 \times 290}{0.814}$

$I = 117.56$ $Kg. m^{2}$

Find the momentum inertia of disk,

$I = \frac{1}{2} Mr^{2}$

$M = \frac{2I}{r^{2} }$

$M = \frac{2 \times 117.56}{(0.330)^{2} }$

$M = 2159.045$ Kg

Therefore, the mass of the wheel is 2159.045 kg
