Question
A man of mass ′m′ climbs on a rope of length L suspended below a balloon of mass M. The balloon is stationary with respect to ground. If the man begins to climb up the rope at a speed vrel (relative to rope). In what direction and with what speed (relative to ground) will the balloon move?
Options
A.downwards,
B.upwards,
C.downwards,
D.downwards,
Solution
vcm = 0
mvB + m (vB + vrel) = 0
∴ vB = −
- sign means baloon moves downward
mvB + m (vB + vrel) = 0
∴ vB = −
- sign means baloon moves downward
