Horizontal spring oscillating at a certain frequency
A 255 g mass attached to a horizontal spring oscillates at a frequency of 2.50 Hz . At t=0 s , the mass is at = 4.40 cm and has vx = -32.0 cm/s . Determine:
1 The Period2 The Angular Velocity3 The Amplitude4 The Phase Constant

The thrust of the skis is parallel to the skis. There is no friction on the slope, and air resistance can be ignored.
Consider the reaction: 200.00mL of 0.125M Pb2+(aq) is mixed with 400.00mL of 0.175 M Cl- (aq). PbCl2 forms. What's the limiting reactant and how many grams of PbCl2 forms and precipitates out of the solution?

The following data show the number of fruit fly killed at varying concentrations of nicotine. The number of ies killed in n exposures can be assumed to follow a binomial distribution
Fit both logistic and probit models, modelling proportion killed as a function of nicotine concentration. Are there any obvious differences in the fit of these models?
5.00mL of such solution is pipetted into a clean 100.00mL flask and diluted with water to the mark. What's the concentration of this solution?
Using the models in (a), estimate the nicotine concentration that would kill 50% of flies. Also estimate the dose hat would kill 90% of flies.
The windows in an office building are 4.26 m by 5.26 m. On a stormy day, air is blowing at 53.0 m/s past a window on the 53rd floor. Find the magnitude and direction of the net force on the window. The density of air at that height is 1.23 kg/m3.
