A block having a mass of0.72 kg is given an initial velocity vA = 1.3 m/s to the right and collides with a spring whose mass is negligible and whose force constant is k = 45 N/m as shown in the figure. The spring is now mounted vertically on the table, and the mass is dropped downwards, hitting the spring and compressing it. Just before the "collision", the block has a measured velocity of 2.00 m/s downwards. What will be...

A mass m=29.0 kg slides on a frictionless track with initial velocity vA=16.5 m/s at Position A with height hA=53.1 m. It passes over a lower hill with a height hB=26.4 m (at Position B) before stopping by running into a large spring with spring constant k=5058 N/m at Position C at height hC=23.5 m. The mass is brought to a stop at Position D, after compressing the spring by a length of d. Find the speed of the object...

A body of mass 15.0 kg is traveling at 5.3 m/s along the positive x-axis with no external force acting. At a certain instant an internal explosion occurs, splitting the body into two chunks of 7.5 kg mass each. The explosion gives the chunks an additional 16 J of kinetic energy. Neither chunk leaves the line of original motion. Determine the speed and direction of motion of each of the chunks after the explosion. Enter the larger velocity. Enter the...
