<span>The answer in the space provided is drive error. It is because not only that hard braking or abrupt acceleration causes skids, but it is also caused by a driving error where in the individual is likely to cause the skid when he or she cause a driving error.</span>

Answer: travelling too fast, doing a very aggressive or sudden turn, or bad conditions of the road.

Explanation:

Skidding is the slip of the wheels over the road caused by loss of traction between the tires and the pavement.

When the tires slip, they lose their grip on the ground and tend to move according to the inertia or the imperfections of the surface instead of following the desired route. So, the driver is not in control of the vehicle any more.

The traction is how hard the wheels are attached to the ground, whenever you are forced to brake hard, accelerate abruptly, make a sudden turn or the surface of the road is covered with water, sand, or oil, the wheels will not adhere enough to the road and the car skids.

Also the conditions of the tires are important: when the tires lose their design, they will not have the capacity to displace the water and will slide easilyover wet surfaces.

A horizontal circular platform (m = 119.1 kg, r = 3.23m) rotates about a frictionless vertical axle. A student (m = 54.3kg) walk
Murrr4er [49]

Answer:

\omega_2=5.1rad/s

Explanation:

Since there is no friction angular momentum is conserved. The formula for angular momentum thet will be useful in this case is L=I\omega. If we call 1 the situation when the student is at the rim and 2 the situation when the student is at r_2=1.39m from the center, then we have:

L_1=L_2

Or:

I_1\omega_1=I_2\omega_2

And we want to calculate:

\omega_2=\frac{I_1\omega_1}{I_2}

The total moment of inertia will be the sum of the moment of intertia of the disk of mass m_D=119.1 kg and radius r_D=3.23m, which is I_D=\frac{m_Dr_D^2}{2}, and the moment of intertia of the student of mass m_S=54.3kg at position r (which will be r_1=r=3.23m or r_2=1.39m) will be I_{S}=m_Sr_S^2, so we will have:

\omega_2=\frac{(I_D+I_{S1})\omega_1}{(I_D+I_{S2})}

or:

\omega_2=\frac{(\frac{m_Dr_D^2}{2}+m_Sr_{S1}^2)\omega_1}{(\frac{m_Dr_D^2}{2}+m_Sr_{S2}^2)}

which for our values is:

\omega_2=\frac{(\frac{(119.1kg)(3.23m)^2}{2}+(54.3kg)(3.23m)^2)(3.1rad/s)}{(\frac{(119.1kg)(3.23m)^2}{2}+(54.3kg)(1.39m)^2)}=5.1rad/s
