On a frictionless horizontal surface, a block is pushed up against a 14,025 N/m spring and compresses it 0.22 m. The block is then released and upon leaving the spring it is going 11 m/s. A.) Determine the block's mass. m = B.) The block then moves up a hill that is not frictionless. Determine what height the block reaches if 159 J of thermal energy is produced. h =

Suppose a unidirectional vector field E exists across an enclosed surface A as shown below. which among the following is/are true? 153 E The divergence volume integral value will only be equal to 0 if E is a uniform field. O The divergence volume integral value will be positive if the magnitude of E is increasing along the positive z-hat direction. The divergence volume integral value will always be equal to 0. Only the top and bottom cylindrical phases have non-zero divergence surface integral values.
