Projectile motion-stroboscopic representation (1 Viewer)

[yxs]

Hi Guys!

We are having our half-yearly Physics Prac Exam on Monday, the topic is on projectile motion.

I'm almost certain that we'll be given a stroboscopic representation of a projectile and asked to calculate the maximum range, velocity etc from it.
I understand the concept of projectile motion but I don't understand the stroboscopic representation of a project at all...!

for example. how does a 12.5Hz stroboscopic representation different to a 10Hz one? and how do you calculate the time intervals between each of the dots?

I would be really grateful if someone could please explain to me=D!

Thanks in advance =D

T = 1/f

12.5Hz corresponds to a time between each dot of 1/12.5 = 0.08sec

10Hz corresponds to a time between each dot of 1/10 = 0.1sec

Thank you very much=)

Sorry, do you know where I could find past papers on projectile motion prac or the motor effect prac for motors and generators?

Thank you=)
