A golf ball is hit off a tee at the edge of a precipice.?

A golf ball is hit off a tee at the edge of a precipice. X and y coordinates versus time are given by the following expressions. x = (18.0 m / s) and t = (4.30 m / s) t – (4.90 m / s ^ 2) t ^ 2 (a) Write an expression vector of the position of the ball as a function of time using the unit vectors i and j. (Use T, i and j as necessary.) R = _______________m (b) In taking derivatives, obtain an expression for the velocity vector v as a function of time. vm = ______________ / s (c) By taking derivatives, obtain an expression for the acceleration vector function of time. _____________ A = m / s 2 (d) Next unit use vector notation to write an expression for the position of the golf ball at t = 2.00 s. r (2.00 s) = ______________( m) i +______________ (m) j (e) Write an expression for the velocity at this time. v (2.00 s) = ____________( M / s) i + ___________( m / s) j (f) Write an expression for the acceleration at this time. one (2.00 s) =______________ (m / s ^ 2) j
