A gymnast of mass 55.0 hangs from a vertical rope attached, Ask an Expert

Academics

Q1. A gymnast of mass 55.0 hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value for the acceleration of gravity.

Calculate the tension in the rope if the gymnast climbs up the rope with an upward acceleration of magnitude 1.30.

Work out the tension in the rope if the gymnast slides down the rope with the downward acceleration of magnitude 1.30.

Q2. Two narrow slits are 20 wavelengths apart are illuminated with light of wavelength lambda. What is the angle of bright fringe in radians between the central maximum and the m=1 and m=-1 bright fringe?
