A jet plane lands with velocity of 100m/s and can accelerate at a maximum rate of -5m/s2 as it come to rest. From the instant it touches the runway, what is the minimum time needed before it stops?

An automobile steering wheel is shown. what is the ideal mechanical advantage? if the ama is 8, what is the efficiency of the steering wheel?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

The force it would take to accelerate an 900-kg car at the rate of 6m/s2
