A marksman fires a practice round from A toward a target B. If the target diameter is 160 mm and the target center is at the same altitude as the end of the rifle barrel, determine the range of "shallow" launch angles for which the round will strike the target. Neglect aerodynamic drag and assume that the round is directed along the vertical centerline of the target. (Note: The word "shallow" indicates a low-flying trajectory for the round.)

To solve the exercise, you must use equations of dynamics, the speed of bodies of mass m1 and m2 after they have traveled a distance "d". Consider the pulley with mass M and radius R. It must be solved using both methods. The masses are equal and of different angles. Show the answer with pictures.
A marksman fires a practice round from A toward a target B. If the target diameter is 230 mm and the target center is at the same altitude as the end of the rifle barrel, determine the range of "shallow" launch angles for which the round will strike the target. Neglect aerodynamic drag and assume that the round is directed along the vertical centerline of the target. (Note: The word "shallow" indicates a low-flying trajectory for the round.)

The tank is to be placed on a hill that is 1 km high above the ground. The enemy’s base is located at a horizontal distance of 10 km away and it is in a valley 0.5 km below the ground. Air resistance is neglected. Gravitational acceleration is constant and equal to 9.8?/?2 downwards. If the bomb is to be fired perfectly horizontally, what should the launching speed of the bomb be in order to hit the target? What is the duration it would take the bomb to hit the target? Find x(t) and y(t). Consider the initial location of the tank to be (0, 1 km)? Draw the trajectory of the bomb (x and y coordinates). Indicate clearly the value of x (horizontal displacement) when the bomb reaches the ground level. 5. Draw the (?), ??(?), and ??(?) vertical above each other. Indicate key values on the graphs such as the start, the end, the maximum, the minimum and the x and y intercepts. PART 4 and 5 PLEASE.
