Question
please i need help with this question.......... Later in the semester we will calculate the escape velocityfrom various astronomical bodies. The escape velocity is theminimum initial velocity, directed vertically upwards at somedistance R from the center of a planet (orasteroid, star, etc.), that enables an object to coast away (i.e.escape) from that planet. Here, we will estimate the escapevelocity from the earth using only unit analysis. The two physicalquantities that we will use are g, theacceleration due to gravity at the earth's surface, andR, the diameter of the earth. Using these twoquantities, construct a formula with units of velocity, as anestimate for the escape velocity from the surface of the earth.(Note- your estimate, based on nothing but units, is off by onlyabout 40% from the actual answer, which requires a detailed andfairly complex integration
