Referring to Example 8-10 Suppose we would like the landing speed of block 2 to be increased to 1.50 m/s. (a) Should the coefficient of kinetic friction between block 1 and the table-top be increased or decreased? (b) Find the required coefficient of kinetic friction for a landing speed of 1.50 m/s. Note that m1 = 2.40 kg, m2 = 1.80 kg, and d = 0.500 m.
Step 1 of 5
In the given case, we need to comment whether the coefficient of kinetic friction between the block and table top must be increased or decreased in order to increase the landing speed of block 2 to 1.50 m/s.
Here the coefficient of kinetic friction between the block 1 and table top must be decreased in order to have greater kinetic energy of the system and which in turn results in the greater landing speed equal to 1.50 m/s.
