Gibbons, small asian apes, move by brachiation, swinging below a handhold to move forward to the next handhold. a 9.0 kg gibbon has an arm length (hand to shoulder) of 0.60 m. we can model its motion as that of a point mass swinging at the end of a 0.60-m-long, massless rod. at the lowest point of its swing, the gibbon is moving at 3.2 m/s .
what upward force must a branch provide to support the swinging gibbon?
express your answer to two significant figures and include the appropriate units.
(textbook is college physics by: knight, jones, and field.)

= mass of the gibbon = 9.0 kg 
= arm length of the gibbon = 0.60 m 
= speed of gibbon at the lowest point of swing = 3.2 m/s 
 = weight of the gibbon in downward direction 
= Upward force provided by the branch

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
