2. Block m1 in the figure below has a mass of 6 kg and m2 has a mass of 1.4 kg. The coefficient of kinetic friction between m2 and the horizontal surface is 0.55. The inclined plane is frictionless. a. Draw a free body diagram for both blocks.
b. Find the tension in the cord and the acceleration of the system.
c. If the coefficient of static friction is 0.65, what is the minimum mass of block m2 that would prevent the system from moving?

answer and explanation;

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.
