Problem 1: A book is resting on a frictionless table until someone suddenly starts applying a constant force on it right until it reaches the end of the table. The book was constantly accelerating until it reached the end of the table. First, write down your thinking process as in the previous example, and then draw in the space provided below the book's motion diagram along with the velocity, acceleration, and force vectors. Draw book's motion diagram with velocity, acceleration, and force vectors. (Hint: Since the motion is horizontal, draw a horizontal motion diagram.)
Blocs A, B, and C are placed as in the figure and connected by ropes of negligible mass. Both A and B have masses equal to 2.0 kg and the coefficient of friction between each block and the surface is 0.35. Block C descends with the constant velocity. a. Draw three separate free-body diagrams showing forces acting on block A, B, and C. b. What is the tension in the rope connecting blocks A and B? c. What is the mass of block C? с. d. If the rope connecting A and B were cut, what would be the acceleration of C? 36.9°

A block m1 rests on a frictionless surface. A second block m2 sits on top of the first block. Here m1 = m2 = m. A horizontal force F is applied to the bottom block to pull it to the right as shown below. Assume that the blocks move together across the surface (block m2 does not slide off of block m1). a.) What is the magnitude of the acceleration of the blocks? (Use the following as necessary: m, g, and F.) a = b.) What are the magnitude and direction of the static friction force acting on m1 due to m2? (Use the following as necessary: m, g, and F.)magnitude: f =direction: c.)

The system moves with constant speed. a. Draw the free-body diagram of the cart and the bucket. b. Write the equations of motion (x-axis) for the cart and (y-axis) for the bucket. c. If the mass of the bucket is 1.5kg. What is the weight of the cart?
Imagine a semi-truck and a minivan are about to collide. The semi-truck obviously has a larger mass, butthe minivan has a larger velocity in this case.a. Do you think each vehicle exerts a force on the other? How can you tell?b. How does the magnitude of force experienced by each vehicle compare? Draw a free-body diagramfor each vehicle to explain your thinking.c. Why does the collision have a greater effect on the minivan than the semi-truck? (Hint: Considerthe acceleration of each vehicle during the collision.)
