A50.0-kg student stands on a 150-kg wooden plank. both start at rest on a frozen pond (assume the interface between pond and plank is frictionless). the student then walks with a constant velocity of 1.10 im/s relative to the plank. (a) what is the velocity of the plank relative to the frozen pond?

Listed below are the measured radiation absorption rates (in w/kg) corresponding to 11 cell phones. use the given data to construct a boxplot and identify the 5-number summary. 1.16 0.85 0.69 0.75 0.95 0.93 1.18 1.17 1.42 0.54 0.57 the 5-number summary is nothing, nothing, nothing, nothing, and nothing, all in w/kg. (use ascending order. type integers or decimals. do not round.)
