Question

Particle in xy plane The position r of a particle moving in an xyplane is given by
r = (2.00t3 - 3.00t) i + (7.00 - 2.00t4) j. Here r is in meters andt in seconds.

(a) Calculate r for t = 1.00 s.
______m i + ______m j + ______m k

(b) Calculate v for t = 1.00 s.
____m/s i + ______m/s j + _____m/s k

(c) Calculate a for t = 1.00 s.
______m/s^2 i + ______m/s^2 j + ______m/s^2 k
