Bài 1. Đoàn tàu khởi hành chạy từ ga Hà Nội lúc 19h00ph. Tàu đến Vinh lúc Oh53ph, đến Tháp Chàm lúc 22h05ph, đến Sài Gòn lúc 4h00ph. Biết con đường tàu đi dài 1720 km và coi như thắng, tìm V?

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

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
