Question
A box of mass m=1.0kg is at rest at point A. AB is a frictionless plane inclined at 30 with respect to the horizontal. BCD is a horizontal plane. At point B there is a smooth transition between the motion on the two planes (i.e. m’s speed just before arriving at B is equal to the horizontal speed just after leaving B). At point C the mass makes contact with an uncompressed spring of spring constant k=480N/m. C is 4m from B. The coefficient of kinetic friction on the segment from B to C is 0.15.d) What is the kinetic energy (in Joule) of the box at B? e) What is the work (in Joule) that friction does on the box during the motion from B to C? f) What is the kinetic energy (in Joule) of the box at C? g) In order to bring the box to a full rest, by how much does the length of the spring get compressed
Explanation / Answer
Please leave a comment with the initial height or length for the plane inclined. It is essential for kinetic energy calculation
