As a body is projected to a high altitude above the earth’s surface, the variation of the acceleration of gravity with respect to altitude y must be taken into account. neglecting air resistance, this acceleration is determined from the formula a = -g0[r2> (r + y) 2 ], where g0 is the constant gravitational acceleration at sea level, r is the radius of the earth, and the positive direction is measured upward. if g0 = 9.81 m> s 2 and r = 6356 km, determine the minimum initial velocity (escape velocity) at which a projectile should be shot vertically from the earth’s surface so that it does not fall back to the earth. hint: this requires that v = 0 as y s .
