1. A golf ball is hit off a tee at the edge of a cliff. Its x and y coordinates versus time aregiven by the following expressions: x = (18 m/s)t and y = (4 m/s)t - (4.9 m/s2)t2. a)Write a vector expression for the ball’s position as a function of time, using the unitvectors i and j. Write expressions for b) the velocity vector as a function of time andc) the acceleration vector as a function of time. Now, write expressions for d) theposition, e) the velocity, and f) the acceleration of the ball, all at t = 3 s.

Question
1. A golf ball is hit off a tee at the edge of a cliff. Its x and y coordinates versus time are
given by the following expressions: x = (18 m/s)t and y = (4 m/s)t - (4.9 m/s2
)t2
. a)
Write a vector expression for the ball’s position as a function of time, using the unit
vectors i and j. Write expressions for b) the velocity vector as a function of time and
c) the acceleration vector as a function of time. Now, write expressions for d) the
position, e) the velocity, and f) the acceleration of the ball, all at t = 3 s.
