Figure 6 . An automobile having a mass of 1000 kg is driven into a brick wall in a safety test.
The bumper behaves like a spring of force constant 5.00 , 106 N/m and compresses
3.16 cm as the car is brought to rest. What was the speed of the car before impact,
assuming that no mechanical energy is lost during impact with the wall?

(a) Two waves traveling in opposite directions produce a standing wave. The indi-
vidual wave functions are
yı = 4,0 sin(3.0x – 2.0t)
Y2 = 4.0 sin(3.0.0 + 2.0t),

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.

Abanked road comer of radius 146 m is to be constructed. if the comer is designed for vehicles moving with a speed of 20.0 m/s, what should the banking angle be, in units of degrees?
