12. you take a trip to dallas, 446km from san antonio. if it took 6 hours and 30 minutes (there was
a wreck in austin, of what was your average velocity to dallas? let's say you take the
highway 130 toll road coming back and you average 105km/hr. how long did it take you to get
from dallas to san antonio? note: remember, it asked for velocities, so what do you need to
have a complete

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
