(b) A rocket is moving at constant speed upwards. Do not ignore air resistance. (c) A box is sitting in the back of a moving truck when the truck slams on its brakes. The box does not move in the bed of the truck. (d) A soccer ball being kicked by you. Your foot and the ground are still in contact with the ball. (e) The soccer ball of the previous part is now in the air, do not ignore air resistance.

O řr and Fa and Ě, Submit Request Answer Usually the best advice is to choose a coordinate system so that the acceleration of the system is directly along one of the coordinate axes. If the system isn't accelerating, then you are better off choosing the coordinate system with the most vectors along the coordinate axes. But now you are gaing to ignore that advice.…
An exporter arrived with his goods at the Panama Canal; he was informed by the official manning the canal that the vessel carrying his goods would be towed along the canal. The rope that is used to tow the barge is inclined at 20⁰at the direction of the canal. The tension in the rope is 200N. i.Sketch the set-up narrated above. ii.Show the steps that are taken to determine the values of the rectangular components of the tension, one component being in the direction of the canal
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.)
Two masses B and C are connected with a string passing over a friction less pully, assuming the coefficient of friction between the table and block is μ=0.4 , and the acceleration of gravity g=9.81 m/s2.

Find an expression of the acceleration of the two masses in terms of ?? and ??.C. Determine the tension in the rope in terms of ?? and ??.D. If ??= ʎ kg, ?? = (ʎ-5) kg, determine the acceleration of two blocks and the tension in the rope.(ʎ= the final two numbers of your ID +10, and, gravitational acceleration, g = 9.81 m/s2).

Learning Goal: A box of mass 3.0 kg slides down a rough vertical wall. The gravitational force on the box is 29.4 N. When the box reaches a speed of 2.5 m/s, you start pushing on one edge of the box at a 45° angle (use degrees in your calculations throughout this problem) with a constant force of magnitude F₂ = 23.0 N, as shown in (Figure 1). There is now a frictional force between the box and the wall of magnitude 13.0 N. How fast is the box sliding 2.4 s after you started pushing on it? Figure 45° F₂ 1 of 1
