A school bus is travelling at 4 m/s. Its velocity then increases to 12 m/s. Calculate the average velocity of the bus over the journey. Final velocity = 12 m/s. Initial velocity = 4 m/s. Average ...

A car can accelerate from 22 m/s to 30 m/s in 4 seconds. Calculate the acceleration of the car. Final velocity v = 30 m/s. Initial velocity u = 22 m/s. The final velocity v – initial velocity u = 30 m ...

One of the most important issues facing companies both in the Internet space and otherwise, is how to price their products. We've found that one of the best ways to help companies with the pricing ...

Abstract: Estimating angles for coherent signals remains a critical challenge in array signal processing. Traditional spatial smoothing techniques can recover the rank loss caused by signal coherence, ...

Self-motion can facilitate perspective switches and “automatic spatial updating” and help reduce disorientation in applications like virtual reality (VR). However, providing physical motion through ...
