1.) If A= 2i + 4j - k and B= i + 2j + 3k , find the product of the two vectors.

2.) An airplane travels 209 km on a straight course at an angle of 22.5° East of North. It then changes its course by moving 100 km North before reaching its destination. Determine the resultant displacement of the airplane.

3.) Calculate the average velocity given 6.00 m and 8.00 m respectively and its time interval t= 2.00 s to 5.00 s.

4.) A particle is in motion and is accelerating. The functional form of the velocity is v(t) = 2t^2 - 4t +69 . Determine (a) the instantaneous acceleration at t= 2, 4, 6 s
and (b) the instantaneous velocity at t= 2, 4, 6 s.
