An elastic band is hung on a hook and a mass is hung on the lower end of the band. When the mass is pulled downward and then released, it vibrates vertically. The equation of motion is s = 2 cos (t) + 3 sin (t), t > 0, where s is measured in centimeters and t is seconds. (Take the positive direction to be downward.)(a) Find the velocity at time t.(b) Graph the velocity and position functions.(c) When does the mass pass through the equilibrium position for the first time?(d) How far from its equilibrium position does the mass travel?(e) When is the speed the greatest?

The lengths of nails produced in a factory are normally distributed with a mean of 4.91 centimeters and a standard deviation of 0.05 centimeters. find the two lengths that separate the top 4% and the bottom 4%. these lengths could serve as limits used to identify which nails should be rejected. round your answer to the nearest hundredth, if necessary.
