A cyclist travels with a speed of 36 km^(-1)if the angleof inclinatio

1.	A cyclist travels with a speed of 36 km^(-1)if the angleof inclinatio withvertical is 45^(@)whilehe goes around a circle then the radius of the circle is
Answer» 7m 10 m 5.5 m 20 m Solution :`v=36 xx (5)/(18) =-10 ms^(-1)` `:. R = (v^(2))/( g TAN theta )= (10 xx 10)/( 10 xx tan 45^(@))` `= (100)/(10 xx 1) = 10 m`
