(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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 x-axis and a line tangent to its path at t=25 s

2. Relevant equations

I have no clue what to do!

3. The attempt at a solution
