A 15 kg block is sliding across the ground. The block starts with a speed of 20 m/s. The block stops after sliding 10 m. a) What is the acceleration of the block? b) What is the force of friction on the block? c) What is the coefficient of friction between the block and the ground? Remember to include the following when answering these questions: What did you get? (your answer with the correct units and supporting work) How did you get that? (the equation you chose to use to get your answer) Why did you use that? (the concept that supports the use of the equation that you chose to use) Edit View Insert Format Tools Table 12pt v Paragraph v BIUA 2v T? v: I.

Work and Kinetic Energy Q5: Please answer each part step by step and explain each step (even if minor)  in detail please.

Please draw an LOL diagram. I gave an example of it.

Two blocks are connected by a very light string passing over a massless and frictionless pulley (Figure 1). Traveling at constant speed, the 20.0 N block moves 80.0 cm to the right and the 12.0 N block moves 80.0 cm downward. Part E During this process, how much work is done on the 20.0 N block by friction? Express your answer with the appropriate units. HẢ ? Wf, 20.0 N = Value Units Figure 1 of 1 Submit Request Answer Part F 20.0 During this process, how much work is done on the 20.0 N block by the normal force? N Express your answer with the appropriate units. ? 12.0 N Wn, 20.0 N = Value Units

The class I'm taking is physics for scientists and engineers! I have attached the problem below! Please view both attachments before answering. If you can please explain your answer so I can fully understand. Thank you so so much!

If a force of 60 N stretches a spring 0.5 m beyond its natural length, how much work does it take to stretch the spring 5.5 m beyond its natural length? The amount of work done is J. (Simplify your answer.)
