Physics 100 – Fall 2007 “skater” A constant force is exerted on a “skater” that is initially at rest on “ice” – an air track. The force acts for a short time interval and gives her a certain final speed. To reach the same final speed with a force that is only half as big, the force must be exerted for a time interval A. four times as long as B. twice as long as C. equal to D. half as long as E. a quarter of that for the stronger force. Answer: B
