Soit une course d'automobiles de 500 km sur un circuit de 10 km. Le véhicule A termine la course en
4 h avec 1,5 tour d'avance sur le véhicule B. Combien
de temps aura mis le véhicule B pour franchir les
500 km de la course?

spare some change and give it to the poor

explanation:

plz : ((

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
