3) So, James makes it to the other side, but obviously doesn’t catch Kevin. He decides to go back to the lab and test some other ideas. One involves pulleys, rope, and blocks. He sets up a system of pulleys as shown. The coefficient of kinetic friction on the table is 0.12. a) What is the acceleration of the three objects? b) What is the tension in each of the two strings? (SHOW ALL WORK, UNITS AND FORMULAS USED)

A 25 kg child goes down a straight slide inclined 40 degrees above the horizontal. The coefficient of kinetic friction between the child's shorts and the slide is 0.25.  A) Draw a free body diagram for the child on the slide in your written work. Indicate a useful coordinate system. B) What is the acceleration of the child as she goes down the slide?

Hi, please show full solutions and also explain how you get the answers in physics terms so it's understandable. The correct final answers are written beside too. Thank you. A slider approaches a ramp that is sloped up at an angle of 10.0º at a velocity of 6.0 m/s. The coefficient of friction between the slider and the ramp is 0.2. How far up the ramp does the slider slide? (5.0 m)

Use the figure to answer the question Two blocks are positioned on surfaces, each inclined at the same angle of 57.5 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 5.50 kg, and this time there is NO friction. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2?   a. 7.94 kg   b. 4.00 kg   c. 11.91 kg   d. 5.29 kg
