# Help Again - Gr 12 Physics

hey again,
still looking for projectile motion + circular motion problems (only in horizontal plane). Can anyone please help me make up a question with these two concepts in one. If possible make it a 5 STAR complex question!

I am also studying charged particles in a electric field which relates to circular motion and i am also studying SIMPLE HARMONIC MOTION. Any good complex / exam type questions you can offer will be very much appreicated!

thanks

hey
studying gr 12 physics
also, thanks for the sites you provided, but already studied that last year
still looking for a "CONICAL PENDULUM" problem

would you have any idea to combine a projectile + circular motion problem together ?

What if you had a paticle on a string under vertical circular motion and the string snapped at a given point.

You can make up a question with you throwing a rock which is attached to a string with another rock at the other end.... then you can calculate stuff like it's speed relative to the ground... etc...

It's very elementary, but hmm.

if it snapped, the particle would continue at a tangent,
do you think you could combine SHM+CIRCULAR MOTION+PROJECTILE MOTION all in one question?

Circular motion is an example of SHM.

Yes, but if the circle was vertical you could calculate it's range/flight time, because there would be verticle acceleration due to g.
