1. Find the component of vector A along vector B. Given A = -5i-j and B=i +3j. 2. Find the angle between the vectors A and B where A = -j+k and B =-i-j. 3. A force of 55 N acts at an angle of 275°. Express the force in component form. 4. Two forces are given by Fi = i +j and F2= i-j. Find the magnitude and direction of the resultant force. 5. Two forces are given by F1 = -3i -j and Fz= i+7j. Find (Fix F2). 6. A tree grew to a height of 368 ft in 20 years. Express the growth rate in microns per second. 7. The position of a particle moving along the x axis is given by x = 2t-2t+1. Find its position, velocity and acceleration at 5 s.
