What is its maximum height? If a ball is thrown into the air with a velocity of 40 ft/s, its height in feet is given by y = 40t - 16t^2 Use the formula \lim_{h\rightarrow 0} \frac{s(2+h)-s(2)}{h} to find the exact value of the v Find a general expression...
a本课题根据常规炮弹各阶段的受力分析,并考虑地球曲率、哥氏效应等因素,分别建立相应的质点运动方程; This topic basis convention shell various stages stress analysis, and considered the curvature of the earth, factors and so on elder brother effect, establish the corresponding particle motion equation sepa...
Another approach to the parabola problem, which may be of particular interest to calculus students, is that for a parabola to be the graph of y=ax^2+bx+c: c is the y-intercept (ie the height at the point where x=0) b is the slope of the tangent line at that point, and ...
Projectile motion First, let's do some physics: As usual, F= ma. However, in this case, there are two components for the force, F_x and F_y. Both would experience air resistance, f. The magnitude f of the air drag force is approximately proportional to the square of the projectile’...
Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. As a plane curve, it may be defined as the path of a point moving so that its distance from a fixed line is equal
