A 2000 kg car takes a round turn of radius 40 m with a velocity of $36 \mathrm{~km/h}$. The centripetal force is

Professor PC Thomas Classes · Answer

Convert velocity to m/s: $v = 36 	imes \frac{5}{18} = 10 \mathrm{~m/s}$. The centripetal force is $F = \frac{mv^2}{R}$. Substitute the values: $F = \frac{2000 	imes (10)^2}{40} = \frac{2000 	imes 100}{40} = 5000 \mathrm{~N}$.
