Now assuming negligible aerodynamic drag, the equations governing the "flight" of the ball are given as: x = xo +Voxt 1 29t² y = yo + Voyt - The first of these equations can be used to isolate t and express it as a function of x (as done in class). Then this expression for t can be substituted into the second equation to obtain an equation for y as a function of x (as done in class). Finally, this equation can be simplified and put into the standard form of: y = ax² + bx + c Perform this process and compare the result to the trendline equation to determine the "launch" speed of the ball Vo.

I do not know how to get started with my graph. Does my x axis need to be between 7.84 or 15.68 and my y axis between 0.779 or 1.558. If so how should I start my graph and how much should I go up by with both x and y axis's. Please help! I am confused.

A vector a of magnitude 17 units and another vector b of magnitude 8.5 units differ in directions by 72°. Find (a) the scalar product of the two vectors and (b) the magnitude of the vector product a×b.

A particle of mass m has a time-dependent position vector r(t) = (Rcos(ωt),Rsin(ωt),αt) in Cartesian coordinates, where R, ω and α are positive constants. What are the physical dimensions of R, ω and α? Show that the speed of the particle is constant. Does it mean that the acceleration is zero? Justify.
