1.	A race car negotiates a curve of radius 50.0 m on a flat road. What is its angular displacement when it covers a linear distance of 78.5 m?
Answer» SOLUTION :RADIUS =r=50.0 m Linear distance = s = 78.5 m ANGULAR displacement = `theta` = ? `theta = s/r = (78.5)/50 = 1.54` radian `=360/(2pi) XX 1.54 = 90^(@)`
