An automobile of mass 1.46 e3 kg rounds a curve of radius 25.0 m with a velocity of 15.0 m/s. the centripetal force exerted on the automobile while rounding the curve is

13,140N

Explanation:

Centripetal force (CF) = mv^2/r

Mass(m) = 1.46×10^3, velocity (v) = 15m/s, radius (r) = 25m

CF = (1.46×10^3 × 15^2)/25 = 328500/25 = 13,140N

v 154.9= 0.9 length length s little over 154.9cm

we need to know the time interval during which the force acts. impulse of force = momentum change
