    How Do You Calculate Angle and Velocity in Particle Motion Analysis?

    Homework Statement the position "r" of a moving particle moving in an xy plane is given by r=(2.00(t^3) -5t)î+ (6.00-7.00(t^4) )j with r in meters and t in seconds. In unit notation calculate: A) R B) Velocity C) R when t is 25 seconds What is the able between the positive direction of the...
