A dog goes through a park. Its displacement is described by the following equations: x(t) = 28.0 + 7.2t -0.31t 2 and y(t) = 30.0 -9.1t + 0.22t2 Positions and time are expressed in m and s, respectively. a) At t = 15 s, determine the position vector r of the dog in terms of unit vectors i and .k b) Determine for t = 15 s the velocity vector v of the dog terms of the unit vectors i...

A1. For problem 21.57, write a formula for the position vector
of the electron as a function of time,
r⃗(t)r→(t), using unit vector ("i-hat"
and "j-hat") notation. Assume the electron starts at the origin of
your coordinate system at t = 0, so
r0→=0iˆ+0jˆ.
