An object of mass 4.00 kg is sitting at the top of an inclined plane of height h and angle  with the horizontal. The object slides down the inclined plane and right before it reaches the bottom of the plane, it has speed of 16.0 m/s.
 
  Neglect friction and use g = 10.0 m/s2. (a) What is the height of the inclined plane? (b) If the height of the inclined plane is raised to 15.0 m, what is the speed of the object right before it reaches the bottom of the inclined plane?

Question 2

A mass of 1.0 kg is pushed against a spring with a spring constant of 25 N/m. As a result, the spring is compressed by 20 cm. The mass is then released.
 
  (a) What is the amount of potential energy acquired by the spring when it is compressed?
  (b) What is the kinetic energy of the mass after the mass is released and it is no longer in contact with the spring?
