Question

A spring that lies along X axis is attached to a wall at end and block at the other end. The block rests on a frictionless surface at X = 0 then an applied horizontal force F of constant magnitude begins to compress the spring, displacing the block by distance X, untill the block comes to maximum displacement Xmax. Which of the curves in figure best represent

The kinetic energy of the block

  1. curve–1    
  2. curve–2    
  3. curve–3    
  4. curve–4    

The correct answer is: curve–1

A block of mass m sliding down an incline at constant speed is initially at a height h above the ground, as shown in the figure above. The coefficient of kinetic friction between the mass and the incline is m. If the mass continues to slide down the incline at a constant speed, how much energy is dissipated by friction by the time the mass reaches the bottom of the incline?

In figure shown on the right, the mass of the trolley is 100 kg, and it can move without friction on the horizontal floor. Its length is 12m. The mass of the girl is 50 kg. Friction exists between the shoes of the girl and the trolley’s upper surface, with mu = 1/3. The girl can run with a maximum speed = 9 m/s on the surface of the trolley, with respect to the surface. At t = 0 the girl starts running from rest to the right. The trolley was initially stationary.(g = 10 m divided by s to the power of 2 end exponent )

At a certain moment when the girl was accelerating, the earth frame acceleration of the trolley is found to be 1 m/s2 At this moment, the friction force between the girl’s shoes and the trolley’s surface is
