The block enters a rough section at B, extending to E. The coefficient of kinetic friction is 0.36. When the block is at rest, static friction act upon it which prevent the block from movement but when the block start motion, this static friction replace by the kinetic friction which opposes the moving body and reduce the speed.

What is the slope of the line with equation y3=(x2)? Hint: Use the energy equation to find $\Delta h$. If we compare the opportunity costs and possible gains from trade for Juan and Wanda, we can determine the exact exchange ratio at which the parties will agree to trade? After the block reaches its highest point, it slides back down, but the magnitude of its acceleration is less on the descent than on the ascent. But when the block is sliding down the ramp, the friction and the parallel component of the weight act in opposite directions, resulting in a smaller magnitude net force. ), the average high temperature for days in July has a mean of 28.9 Celsius with a standard deviation of 3.3 Celsius. the smaller block at one end of the larger block.
