Really TRUE odd factoids

[markemark]

Question - is it possible to instantaneously reverse your direction of travel? Will there always be a slowing down period, a period of rest then a period of acceleration in the opposite direction?

Instant change in velocity would infinite acceleration and as such impossible as any object with mass would require and infinite force to do so.

Now, objects without mass would be something to think about.

It’s cheating, but if you drive at 30mph, and shoot a ball to your rear at 30mph, it stops and falls to the ground.

It’s cheating, but if you drive at 30mph, and shoot a ball to your rear at 30mph, it stops and falls to the ground.

The ball deccelerates on shooting based on the power of the gun from 30 to 0 over a period of time. It’s not instantaneous.
