The Time in Seconds That It Takes for a Sled $\theta$

question 85

Short Answer

The time in seconds that it takes for a sled to slide down a hillside inclined at an angle $\theta$ is $t = \sqrt { \frac { d } { 16 \sin \theta } }$ where d is the length of the slope in feet. Find the time it takes to slide down a 4000-ft slope inclined at $30 ^ { \circ }$
