An object is moving under a constant acceleration (never changes at any point). it is initially moving in the +x direction at 7 m/s. after some time the object stops and then starts moving in the -x direction. after a total time of 9 seconds, its average velocity for the entire trip is 8 m/s in the -x direction. how much distance does the object cover in this time in meters?

learn it on the intertant so you can solve

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
