a) Since decimals are just another name for a fractional quantity, it shouldn’t matter which form of the numbers you use to do a problem. To illustrate this, do the following problem using the decimal form of the numbers.
4.2 + 1. 35 =
b) Now, change the above problem to the fractional equivalent and do it using fractions, and show that the answer is the same.
A string exerts a tension force on a block (mass m) horizontally. The horizontal surface underneath the block is rough with coefficient μs.
(a) If the tension in the horizontal string is T0, then what is the magnitude of the static friction force? Your answer will be in terms of some or all of the given variables. (Hint: The answer is not μsmg.)
