Solve the Problem $t$ (In Seconds) Required for a Block to Slide Down an (In

question 150

Multiple Choice

Solve the problem.
-If friction is ignored, the time $t$ (in seconds) required for a block to slide down an inclined plane is given by the fc
$$t = \sqrt { \frac { 2 a } { g \sin \theta \cos \theta } }$$
where $a$ is the length (in feet) of the base and $g \approx 32$ feet per second per second is the acceleration of gravity. How long does it take a block to slide down an inclined plane with base $\mathrm { a } = 14$ when $\theta = 30 ^ { \circ }$ ? If necessary, round the answer to the nearest tenth of a second. mula

• A) 0.4 sec
• B) 2.4 sec
• C) 1.4 sec
• D) 1.1 sec
