The diagram shows a rough inclined plane of length 8.0\,m making an angle of \(30^{\circ}\) with the horizontal. A block of mass 5.0\,kg is released from rest at the top. The coefficient of kinetic friction between the block and the plane is 0.20. (Take \(g=10\;\text{m\,s}^{-2}\)). (a) Determine the speed of the block when it reaches the bottom. (b) Determine the time taken to travel down the plane.

Answer Options

Correct Answer A. speed = 7.2 m/s, time = 2.2 s

B. speed = 8.0 m/s, time = 1.9 s

C. speed = 5.0 m/s, time = 3.0 s

D. speed = 6.5 m/s, time = 2.5 s

Correct Answer

Correct Option:

speed = 7.2 m/s, time = 2.2 s
