Find the velocity, acceleration, and speed of a particle with the given position function.r(t)=(2cos t,3t,2sin t) 相关知识点: 试题来源: 解析 r(t)=(2cos t,3t,2sin t)\ ⇒ \ v(t)=r'(t)=(-2sin t,3,2cos t), a(t)=v'(t)=(-2cos t,0,-2sin t), v(t) =√ (...
These instruments include accelerometers which are devices that measure acceleration. Thus accelerometers can be used to determine the new location of an object that has moved, if you know where it started. Another instrument is the inclinometer, which measures inclination, or how tipped something is...
