A line that describes volume across the surface of an object or shape is called a ____ line.
Sergio039 [100]
A line that describes volume across the surface of an object or shape is called a cross-contour line. These are lines that would reflect the eye's movements of what you see around. These describes form and volume as compared to contour lines which describe edges only. These lines would help in understanding a three dimensional form in a form of 2D.

A NASCAR driver weighing 75 kg enters a corner with a radius of 155 meters. If his acceleration is 100 m/s2. What is tangential
Ymorist [56]

The tangential velocity of the car is 124.5 m/s

Explanation:

The centripetal acceleration of an object in uniform circular motion is given by:

a=\frac{v^2}{r}

where

a is the acceleration

v is the tangential velocity

r is the radius of the circle

For the car in this problem, we have:

a=100 m/s^2 is the centripetal acceleration

r = 155 m is the radius of the turn

Solving for v, we find the tangential velocity of the car:

v=\sqrt{ar}=\sqrt{(100)(155)}=124.5 m/s
