Homework Statement Ok so I am given that a pendulum swings 41.35 seconds in 20 cycles. I have to find the frequency of that pendulum Homework Equations i know that f=1/T where T is period b/c frequency and period are reciprocal to each other. i also know that f = N/t where t is the time...

the rocket is using a b6 engines and is being launched into the air.

Homework Statement ok, so in need to find the force of friction applied onto a model rocket. I don't want the answer, but how to find thr force of friction Homework Equations i know that Ff=μkFn Fn=mg but i don't know how to find μk

the question is related to my model rocket we launched a week ago, the accceleration is average from initial to the max height. don't know if that makes sense.

Homework Statement ok, so i need to find max velocity and force of friction of a model rocket. The rocket weights 83.8 g, accelerates at 5.78 m/ss. Its max height is 84.99 m. please help Homework Equations ok for Ff = μkFn as for Vmax i have no idea The Attempt at a Solution ok...

Please Explain this?! hey, ok so i was going tthrough my textbook and following some examples hwne i cam up to this: Force of Thrust = Ft/ delta T = 6N / 3.48s =1.7 N but it doesn't say what the equation means. can someone...

hey, i have the same question, but what does w stand for? since m = mass, Ft = force of thrust anf a = acceleration (right)? then what is w?

Ok, so i need to find the max height that my rocket travelled, however, the only thin gi got is that a reader holding a clinometer is 50m form the launch site and is 1.78m heigh. According to him, my rocket traveled with a 59 degree in 3.83 sec (taken when the rocket's parachute came out at the...
