Child Advocates is an effective solution to the epidemic of child abuse because our volunteers ensure children exit the foster care system as quickly as possible so they can grow up in loving, permanent homes.
From the surface of the Earth, escape velocity (ignoring air friction) is about 7 miles per second, or 25,000 miles per hour. Given that initial speed, an object needs no additional force applied to completely escape Earth's gravity. Answered by: Paul Walorski, B.A. Physics, Part-time Physics Instructor.
In order to escape Earth's gravity an object must travel around 25000 miles/hour. Different sources cite different velocities. One figure that is cited refers to 24,840 mph (www.library.thinkquest.org). The seven-mile/second figure would produce a velocity of 25200 mph.
