Three blocks are connected, as shown in the figure below, on a horizontal frictionless table and pulled to the right with a force T3 = 65.0 N. If m1= 12.0 kg, m2= 24.0 kg, and m3 = 31.0 kg, calculate the acceleration of the system
The tensions T1 and T2 in the interconnecting cords.

What are similarities and differences between refraction, reflection, diffraction and absorption?

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
