i got .117 for the period 67.1 * 2pi / 60 * 1/60

2pi radians = 1 revolution so that's 60 seconds per 2 pi radiants so that's 10.679 radiants

that was the equation provided by the instructor =(

because trying to find period i would have t = 2 * pi * r / v so the meters from radius and velocity cancel leaving seconds. But i yet to see how weight comes into play

the units on period is seconds but i don't see how i can use revolutions and the weight to obtain the velocity

Circular path---) finding period Homework Statement A 50-g weight tied to a string is twirled in uniform circular motion. If the circumference of the circular path is 207.3 cm and the weight completes 67.1 revolutions per minute, what is the period of the motion, in seconds? Homework...

i feel like I am making a mistake in converting the reference area since the object is falling

if my numbers are correct i arrange the problem 1.56 / (1/2 * 1000*1.55^2 * 10.26) doing the math Coefficient of drag = 1.26e-4?

also converting the Area to m 10.26m is that correct?

air is less dense than water is why i ask

so M * G ---) 1.568 = drag force?

even when in water?

Homework Statement hile playing pool on a cruise ship, you accidentally hit the cue ball over the railing and it falls into the ocean below. If the cue ball (a sphere of diameter = 57.15 mm, m = 160 g) reaches a terminal velocity of 1.55 m/s in the water (), what is the drag coefficient of...

ok so the forces i have acting on the cow are: mgsin(angle) mgcos(angle) mg Friction(going up the incline) N(force) im not sure how to arrive at Fnet because i need the mass to be able to get the components of it

Friction and tension force-- mass Homework Statement In the real world, ramps aren't frictionless, so I had to drag Brisket up a ramp, slanted at 26.6° from the ground, that had a coefficient of kinetic friction = 0.674. I applied a tension force FR=5060.8N to my pet cow using the rope...
