1) A stationary book was placed on a table. Which free body diagram that represent the forces acting on the book? a) W=N b) FR = FP 2) A car is moving in a straight line with a constant velocity. what is the resultant force of the car a) F= 0 N b) F ≠ 0 N c) F = 30 N 3) A box is at rest on inclined plane. What is the net force acting on that body and what Newton's Law does it obeys? a) F = 20 N. Newton's 1st Law of motion b) F = 0 N. Newton's 2nd Law of motion c) F = 0 N. Newton's 1st Law of motion 4) A car is moving with constant acceleration. Given the value of the mechanical force(engine thrust) is 80 N and the frictional force is 10 N. Calculate the value of resultant force on the car. a) F= 90 N b) F= 70 N c) F= 0 N
