This is the case of floating body in the air. According to Archimedes, as parachutist open the weight of the displace volume of air equalize with the weight of the object attached with the parachutist.
Since parachutist falling with constant velocity and falls a distance.
why does a parachutist stop accelerating downward after opening the chute and then fallong some distance
A 44.0 kgkg parachutist is moving straight downward with a speed of 3.90 m/s If the parachutist comes to rest with constant acceleration over a distance of 0.850 mm , what force does the ground exert on her? If the parachutist comes to rest over a shorter distance, is the force exerted by the ground greater than, less than, or the same as in part A? Explain..
A 43.0 kg parachutist is moving straight downward with a speed of 3.70 m/s . If the parachutist comes to rest with constant acceleration over a distance of 0.775 m , what force does the ground exert on her? Express your answer to three significant figures and include the appropriate units. If the parachutist comes to rest over a shorter distance, is the force exerted by the ground greater than, less than, or the same as in part A? Explain.
Just after opening a parachute of negligible mass, a parachutist of mass 91.0 kg experiences an instantaneous upward acceleration of 0.87 m/s2. Find the force of the air on the parachute. magnitude: direction:
A skydiver falls d1= 495 meters in t1 = 7.5 s before opening his parachute After the chute opens, he falls an additional d2 = 750 meters in t2 =91 s. See the figure (a) Enter an expression or the skydiver's average speed v1 during the period before opening the chute in terms of the given quantities.(b) Enter an expression or the skydiver's average speed, v2 during the period after opening the chute in terms of the given quantities. (c) Inter an expression...
A 2 kg mass traveling at 5m/s undergoes a constant acceleration and comes to a stop in 10 seconds. a) what acceleration does it experience? b) how far does it go during the time it is coming to a stop? c) What net force does the mass experience as it comes to a stop? A 75 kg mass accelerates from rest at a rate of 2m/s2 over a distance of 50m a) How fast is it going after covering a...
3. Why does LM curve slope upwards ? 4. Why does IS curve slope downward ?
a: A car is accelerating uniformly from a rest state at 4 m/s^2. What distance does the car travel for 3 secs? b: Two equal and opposite forces of 3.0 N act on an object. What is the unbalanced force on the object? c: A 2kg ball with a velocity of 3 m/s strikes a 1kg stationary ball and the two balls stick together and move after the collision. With what velocity will the balls move after the collision? d:...
why does Pd have a highest oxidation state of 4+? why stop there and not continue? please help!! show your thought process
Why does the water in the earthenware container stop boiling as soon as the pot is removed from the fire, and in the metal vessel it boils for a while?
why
does the addition of triethylamine cause the glowsticks to glow
brighter before they finally stop glowing?
are the following examples of fluorescence or
phosphorescence?
Why does the addition of triethylami finally stop glowing? [4 pts] 4. ine cause the glowsticks to glow brighter before they 5. Are the following examples of fluorescence or phosphorescence? [3 pts] Glowsticks- Glow-in-the-dark stars - Tonic water will glow while under a "black light"
