Glider

Check your numbers. Even a glider made of lead could go 20 centimeters.

Agreed. The listed distance is 20% of the fuselage length. You should be able to scoot it that far.

sorry it is 20 metres range ..... by mistake i typed it in centimetres

sorry it is 20 metres range ..... by mistake i typed it in centimetres

Multiple choice:
a) 20cm
b) 2m
c) 20m
d) 200m
e) 2km
f) 20km

My bet: d) or e)

sorry what i mean is actually 20 metres ... not centimetres..

how much big catapult is needed for launching above mentioned glider up to 20 metres ?

i think rubber catapult cannot be used for this glider launch ??

harsha, can you help us out a little bit?

Is it made of lead as speculated by Usbport in question #1, or is it more like this:

What sort of answer are you looking for? Modulus of elasticity, length and extension load of a rubber band (together with the launch inclination angle)? The design and specification for a steam catapult? Something in between those two?

What question is your instructor asking? That information may speed things up.

i actually want to know how a 98*98*33 cm glider of plastic or fibre material ( weight optional ) can be projected to a distance of 20 metre by use of catapult ??? is it possible practically ... if so what type of elastic band and what length needed??
