A 75.0 kg astronaut connected by a 20 m long tether to a satellite is initially rotating about the satellite at 5.0 m/s. As the astronaut rotates the tether gets wrapped around the satellite. Find the speed of the astronaut when the tether is 7.0 m long.

multiply 2kg by latent heat of vap

ok

explanation:

because growing process had stoped after 4-5 year

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
