The velocity v (in meters per second) of an object that is thrown straight upward with an initial velocity v, is given by v = v. - 9.8t, where t represents time in seconds. If a ball is thrown upward at 30 meters per second, when will its velocity drop to 5 meters per second? Round to the nearest tenth of a second.​

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
