What experiment could work for this?

A man believes that a motorcycle rides faster than the 25mph speed limit everytime it passes in front of his house. The motorcycle is NOT riding faster than 25 mph. How can you prove to the man that the motorcycle rides slower than the speed limit?

With a strap on.

Shoot him off the motorcycle...

...Why are you trying to go to prison again?

Follow the motorbike around for an hour at a constant speed, and record how far he went.

#5

hit the guy off his bike.

#6

measure the distance from one end of the street to the other, get a stop watch, time how long it takes for the guy to pass by, find speed.

Hey you gave me an idea. ty lol

#8

wtf kind of a question is that?(even though i dont know the answer)

#9

Use one of those speedogun thingys? (i have no clue what its called, im referring to those radar guns used by cops to measure the speed of vehicles).

Dude you are amazing thank you very much. I never thought of it . Thank you so much man I really appreciate it.

#11

Radar????

#12

The motorcycle is on the back of a pickup.

Therefore, the motorcycle is moving faster than 25mph, but isn't moving at all.

Stop time, then walk the man over to the motorcycle and show him the speedometer.

I was just thinking the same thing. If you told a cop that there was a motorist that habitualy sped past a perticular area, you could probably get them to post a cop with radar out there.

o wow

Yeah but what if he speeds up, no where in the question does it say that it is going at a constant speed.

**Edit:**Nevermind, as long as the motorbike is always going less than the speed limit it doesn't matter. If it speeds up when it gets past his house though... But I don't think it does. =\

no problem

but average speed should be good enough for this

#20

but average speed should be good enough for this

Average speed isn't neccesarily good enough, if the motorcycles average speed is 25 mph, chances are at one point it went over.

it will still give him the velocity.

which is good enough for what he wants.

besides, if he speeds up and is over the speed limit already, then that tells him that the guy was speeding anyways.

#22

Average speed isn't necessarily good enough, if the motorcycles average speed is 25 mph, chances are at one point it went over.

true.

if the guy had to turn a corner to get onto the street, he would start off slow, and pick up speed.

if he still had an average speed of 25, then he would had to have been moving faster than 25 mph at some point.

of course, the length of the road will determine the amount of variation due to acceleration and whatnot.

alternatively, he could just time the motorcycle when it stops increasing its speed by changing the distance that he times for.

say, a few houses before and after the mans house that needs proof that the motorcyclist is not speeding.

also, i'd like to ask the TS, is this homework or something, or do you have a crotchety old neighbor that hates kids riding by on their fast motorcycles?

#23

Time how fast it takes him to go from one end of the street to the other.

Measure length of street (via google earth's ruler) then do the calculations.

Edit: Who the hell speeds up and down on a clear residential street?

Got it.

He lifts the back wheel, so his speedometer reads whacko numbers over 25 mph, but he actually isn't moving.

Hmm, I don't think there is anyway you can have definative proof.
