(2 Passengers with an unknown total mass climb into the lift. The lift accelerates upwards at 1.25 m.8, while the cable that supports the lift exerts a constant upward force of 7 500 N. Calculate the total unknown mass of the passengers in the lift. 3.4

ok

explanation:

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
