A block is sliding on a level surface of varying materials, and so its effective coefficient of friction is variable, 0.1t, where t is the time in seconds for how long the block has been sliding. If the block was initially moving at 43.5 m/s, then how far does it move in 5.1 s
Answers: 3
and 
.![\Delta s = \frac{(43.5 \frac{m}{s})^{2}}{2 \cdot [0.1\cdot (5.1 sec)]\cdot (9.807 \frac{m}{s^{2}} )}](/tpl/images/0530/2661/90b23.png)
