What is the acceleration of the 62 kg block if θ = 34, μ _s = 0.4, and μ _k = .3? Round your answer to three significant figures.

If the block starts from rest at the position L = 25 m, how fast will it be traveling when it reaches the bottom of the incline? Round your answer to three significant figures.

Solutions

Expert Solution

The limiting angle is less than the inclined angle so, the block is already in motion so the dynamic friction is considered.

The velocity is found using two methods bothe are explained clearly in below images.

In 4.052 seconds the block will reach to bottom of the inclined plane with acceleration 3.045 m/s2.
