Your friend's 1.41 gram graduation tassel hangs on a string from his rear-view mirror.
(a) When he accelerates from a stoplight, the tassel deflects backward toward the rear of the car hanging at an angle of 6.13 degree relative to the vertical. Determine the tension in the string holding the tassel.
(b) Determine at what angle to the vertical will the tension in the string be twice the weight of the tassel?

A crate of mass 11.5 kg is pulled up arough incline with an initial speed of 1.50 m/s. The pulling forceis 100 N parallel to the incline, which makes an angle of16.0° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate..
Force on a Particle A force F = (4.0 N)i + (c N)j acts on a particle as the particle goes through displacement d = (4.0 m)i - (2.0 m)j. (Other forces also act on the particle.) What is the value of c if the work done on the particle by force F is eac..
an insulated container is filled with a mix of 400 g of water at 20 C and 60 g of ice at 0 C. assuming negligible heat is exchanged with the container, what is the temperature of the mixture when it reaches thermal equilibrium.
