Answer:
1.2 m from the left end
Explanation:
= mass of the person = 90 kg
= mass of friend = 60 kg
= distance of pivot from the person or from the left end
= length of the seesaw board = 3.0 m
= distance of pivot from the friend or from right end = L - r = 3 - r
Using equilibrium of torque about the pivot
Answer:15.8 m/s
Explanation:
Given
Gravitational Force
Air resistance
mass of Parachutist
Velocity after
Now Parachutist opens the parachute
Net for on Parachutist
drag force
therefore deceleration
velocity after 10 s is
