Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

If the uniform cabinet has weight of 200 lb, and the coefficient of static friction between the cabinet and the ground is g = 0.14, determine the minimum force P that can make the cabinet slide. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point and proper unit. Take g = 32.2 ft/s². Your Answer: Answer P 4 ft units A -1 ft-1 ft- 3.5 ft B
Your engineering firm is asked to specify the maximum load for theelevators in a new building. Each elevator has a mass 490 kg when empty and maximumacceleration 2.24 m/s2. The elevator cables can withstand a maximum tension of 19.5 kN beforebreaking. For safety, you need to ensure that the tension never exceeds two-thirds of that value.What is the maximum load that the elevator can safely carry? How many70-kg people is that?Briefly but clearly explain the reasoning for your choice of the sign of the acceleration.

From rest a balloon begins to rise. the Balloon experiences a lift due to a buoyant force of 8000 N. 1. Total massof the balloon is 600kg. Find Acceleration. 2. The balloon rises a distance of 10m and loses a mass of 50 kg after a weight is thrown off. Find the acceleration of the balloon after this weight loss 3. Find the initial velocity of the mass in the vertical direction at the timeof the jump. 4. After falling 10 m, find the mass' final velocity as it comesinto contact with the ground. 5.What is the total time the mass takes to hit the ground? 6. Find the heightof the balloon when the mass hits the ground 7. The mass lands 3 m from the baloon, find the horizontal velocity required to land 3m from the balloon. 8. Since the balloon exeperiences equal forces when the mass is thrown off, what is the horizontal velocity the baloon experiences during this act and how far does the balloon travel when the mass comes into contact with the ground?
