  1. Questions on on forces and vectors

  2. Q1 • An 105 kg object is sliding across a level rough surface. A 400 N force is applied to it and a 50 N friction is created as the object moves. Determine: • The net force on the object • The acceleration of the object • How far the object travels in one minute after it reaches a speed of 3.0 m/s

  3. Q2 • 2 blocks (10.0 kg and 30.0 kg) are connected by a rope on smooth level ground. The 10 kg block is farther right than the 30 kg block. If the 10 kg block is pulled to the right with a force of 100 N: • What are the acceleration of the blocks? • What is the tension on the rope between blocks? • How long does it take for the 30 kg block to reach a speed of 15.0 m/s if it starts from rest?

  4. Q3 • Draw the vector 5 m [S 57 W] • What is it’s equivalent value using polar coordinates?

  5. Q4 • Find the resultant vector of the following displacements: 56 m [N] + 47 m [ W] + 78 m [ E] + 97 m [W] + 27 m [S] + 109 m [W]

  6. Q5 • Find the resultant vector of the following: 97 N [S 37 E] + 135 N (115˚) + 157 N [SW]

  7. Q6 • Determine the force that needs to be added to the forces found in questions #5 in order to produce an equilibrium.

  8. Q7 • What is the equilibrant force of the following: • 198 N [S 48 E]

  9. Q8 • If an object is moving 46 m/s [S] and 67 m/s [W] at the same instant, what is its overall velocity?

  10. Q9 • What are the components of the following displacement? • 149 m [E 15 N]

  11. For homework, do the practice problems 1-9 on pages 121 and 125
