A street car moves rectilinearly from station A to the next station B (from rest to rest) with an acceleration varying according to the law f = a-bx, where a and b are constants and x is the distance from station A. The distance between the two stations and the maximum velocity are

A street car moves rectilinearly from station A (here car stops) to the next station B (here also car stops) with an acceleration varying according to the law f = a - bx , where a and b are positive constants and x is the distance from station A . If the maximum distance between the two stations is x = (Na)/(b) then find N .

Distance between which two stations is second lowest ?

A train goes from rest to rest between two stations with uniform acceleration and retardation. Find the rato of maximum velocity of the average velocity.

A train started from station A and proceeded towards station B at a speed of 48 km/hr. Forty-five minutes later another train started from station B and proceeded towards station a at 50 km/hr. If the distance between the two stations is 232 km, at what distance from station A will the trains meet? 108 k m b. 132 k m c. 144 k m d. none of these

A train starts from station A and reaches B 15 minutes late when it moves with 40 km/hr and 24 minutes late when it goes 30 km/hr. The distance between the two stations is

A train starts from station A with uniform acceleration a_(1) . For some distance and then groes with uniform retardation a_(2) for some more distance to come to rest at station B . The distance between stations A and B is 4 km and the train takes 1//5 h compete this journey. If accelerations are in km per mimute unit, then show that (1)/(a_(1)) +(1)/(a_(2)) =x . Find the value of x .
