A football is thrown horizontally with an initial velocity
Chapter 3, Problem 68GP(choose chapter or problem)
A football is thrown horizontally with an initial velocity of \(\mathrm {(16.6\ m/s)\hat{x}}\). Ignoring air resistance, the average accelerationof the football over any period of time is \(\mathrm {(-9.81\ m/s^2)\hat{y}}\). (a) Find the velocity vector of the ball 1.75 s after it is thrown. (b) Find the magnitude and direction of the velocity at this time.
