A roller-caster vechicle has a mass of 500 kg when fully loaded with passengers (Fig p7.28) (a) If the vechile has a speed of 20.0 m/s at point A, what is the force of the track on the vehicle at this point? (b) What is the maximum speed the vehicle can have at point B in order for gravity to hold it on the track?(adsbygoogle = window.adsbygoogle || []).push({});

a) [tex] a_{c} = \frac{v^2}{r} = 40 m/s^2 [/tex]
