A body starts moving from a point A along the boundaries of a square field as shown in the figure and reaches the point C after 30 s. if its speed is 1 m ` s^(-1)`, what is the shortest distance between A and C ?

Text Solution

Verified by Experts

Distance travelled = 2x
Time, t = 30 s
Speed = `1ms^(-1)`
Speed = `("distance")/("time")=(2x)/30=1`,
`x=30/2` = 15 m
Shortest distance between A and C = `sqrt(15^(2)+15^(2))=sqrt450`
