Question

A spring at top of a 45 degree slope is compressed 0.25 m by a 1.5 kg book. if the book is released, it will just reach the edge of the slope at the spring's equilibrium poiint, and then it will start to slide down the slope. Assume the spring constant is 40 kg/s^2. Assume x-direction and y-direction mean left-right, up-down as usual.
a.) If the slope is frictionless, what will be the speed of the book after it has traveled a distance of 10 meters in the x-direction?
b.) If the book's mass is doubled, does your answer for (a) change, and if so, by how much (b)?

Explanation / Answer

Their velocity after 100m would be 100m/11.25s= 8.88m/s Plug this into the equation vf=vo +at... 8.88 = 0 +a*11.25s a=0.789m/s^2
