Question
n thefollowing figure, two objects located at the identical position on the Indined plane are released from the rest. The box slides without the friction and the bead rolls without sliding. Which of the following statements is/are true? 3 points) ) Since the total forces applied to two objects are different, the mechanical energies of two objects are different b) When two objects reach the bottom the mechanical energies of two objects are equal c) The speeds of two objects at the bottom are equal d) The translational kinetic energy of the bead at the bottom is proportional to the sine of the angle of the inclined plane (sin e) If the bead rolls in the case of identical departure and arival points, the average velocity is constant regardliess of the path 0After the departure, the box is always faster than the bead regardless of the mass g) The box reaches the bottom faster h) If the mass of the box istimes more than that of the bead the speeds of two objects are equal on fowwe the motion of a bead rolling along the inclined plane is measured. WhichExplanation / Answer
Correct statements are
b , e, f, g,
b) Since work done by friction is zero total energy is conserved for bead hence mechanical energy of bead and block are same at bottom.
e) Since displacement is zero average velocity is zero which is constant.
f) Since friction on block is zero its acceleration and hence velocity is greater than bead.
g) Same explanation as f)
