Homework Statement
A particle oscillates in simple harmonic motion with a period of 2.48 s and an
amplitude of 4.24 cm. At t = 0, it is at z = -2.0 cm and it is moving toward
z = 0. We wish to write the position of the particle as a function of time in the following
form, z(t) = A...
Alright, so far I have Fg=(G(2m1))/R2
(2m1 because the masses are equal)
and I'm trying to use C=2\piR
and Ac=v2/R
This is where I start to get a little lost when I'm trying to apply the period somehow to get R. I don't really think I need the centripetal acceleration formula, but...
Gneill, I'm a little confused on how you get the formula for the period without using kepler's 3rd. I just found in my homework instructions that it says to not use kepler's 3rd law. Any advice?
Homework Statement
A binary star system consists of two equal mass stars that revolve in circular orbits
about their center of mass. The period of the motion, T = 25.5 days, and the
orbital speed v = 220 km/s of the stars can be measured from telescopic observations.
What is the mass of...
Homework Statement
A 1540-kg truck has a wheel base of 3.13 m (this is the distance between the front and rear axles). The center of mass of the truck is 1.29 M behind the front axle.
(a) What is the force exerted by the ground on each of the front wheels?
(b) What is the force exerted by...
