What letter shows the ball when it has maximum kinetic energy?

Five structural isomers have the formula c6h14. where needed, draw the structure and give the iupac name of all five isomers.

What are the differences and relationships between speed, velocity, and acceleration

Ablock of mass m1 = 1.75 kg and a block of mass m2 = 5.75 kg are connected by a massless string over a pulley in the shape of a solid disk having radius r = 0.250 m and mass m = 10.0 kg. the fixed, wedge-shaped ramp makes an angle of ? = 30.0? as shown in the figure. the coefficient of kinetic friction is 0.360 for both blocks. (b) determine the acceleration of the two blocks. (enter the magnitude of the acceleration.)
