A car undergoes the folowing displacements: First, 70 km in a direction 30° east of north, then 50 km due south and finally 100 km 30° north of west. If the trip took 2 hours, the average velocity (in km/h) of the car during the trip. Select one O a (-25.8 î+ 30.3 j) km/hr OD (-51.6 î + 60.6 j) km/hr Oc (35 i+ 60.6 j) km/hr Od (-25.8 i+ 80.3 j) km/hr

Answer:
Introduction to the Displacement and Acceleration Equation. It reads: Displacement equals the original velocity multiplied by time plus one half the acceleration multiplied by the square of time. Here is a sample problem and its solution showing the use of this equation: An object is moving with a velocity of 5.0 m/s.
Answer:
The conical Frustum formulas in terms of r and h is as follows: Volume of a conical frustum = V = (1/3) * π * h * (r12 + r22 + (r1 * r2)).In the aerospace industry, a frustum is the fairing between two stages of a multistage rocket (such as the Saturn V), which is shaped like a truncated cone.
...In geometry, a frustum (plural: frusta or frustums) is the portion of a solid (normally a cone or pyramid) that lies between one or two parallel planes cutting it. A right frustum is a parallel truncation of a right pyramid or right cone.
