The position of a particle as a function of time is given by r = (6.50 ihat + 3.10 jhat)t^2 , where t is in seconds.(adsbygoogle = window.adsbygoogle || []).push({});

What is the particle's distance from the origin at t_1 = 2.6 seconds?

What is the particle's distance from the origin at t_2 = 6.2 seconds?

What is the particle's speed at t = 2.6 seconds?

What is the particle's speed at t = 6.2 seconds?

I know that at t = 0 seconds the particle is 0 meters away and has a speed of 0 m/.

How do I go about solving for the other questions?
