.The position of a particle is given by r vector= 3ti-2t2j +4k m, where t is in seconds and the coefficients have proper units for r to be in metres. Find the velocity and acceleration of the particle at t= 2s.

13.A man swims heading right across a river for a length 0.6km in a certain time while the river flows 0.4 km in the same time.Find its resultant motion or change of position.

14.Describing motion in a plane when acceleration is constant.

15. A particle starts from origin t=0 with a velocity 5.0 ^i m/s and moves in x-y plane under action of a force which produces a constant acceleration of (3.0 ^i + 2.0^j) m/s2. (a) What is the y coordinate of the particle at the instant its x coordinate is 84m? (b)What is the speed of the particle at this time?

16. What is relative velocity in a plane?
