falling parachutist you bail out of the helicopter of example 3 and pull the ripcord of your parachute. now in eq. (3), so your

downward velocity satisfies the initial value problem in order to investigate your chances of survival, construct a slope field for this differential equation and sketch the appropriate solution curve. what will your limiting velocity be? will a strategically located haystack do any good? how long will it take you to reach 95% of your limiting velocity?

You bail out of a helicopter and immediately open your parachute, so your downward velocity satisfies the initial value problem.

<h3>What is velocity ?</h3>

Velocity is the rate of change in direction of an item in motion as seen from a specific point of view and as measured by a specific unit of time. In kinematics, the area of classical mechanics that studies how bodies move, velocity is a fundamental idea.

A physical vector quantity called velocity requires both magnitude and direction to be defined. Speed, a coherently derived unit whose quantity is measured in the SI (metric system) as metres per second, is the scalar absolute value (magnitude) of velocity. For instance, "5 meters per second" is a scalar while "5 meters per second east" is a vector.

arzan, who weighs 700 N, swings from a cliff at the end of a convenient vine thatis 20 m long. From the top of the cliff to the
vekshin1

Answer:

= 7.07 m

Explanation:

The Tarzan reaches bottom of swing after descending 2.5 m,

change in his potential energy equals his kinetic energy at bottom of swing

m g h = (1/2) m v²   ,  

hence speed v of Tarzan at bottom of swing is given as  

v = ( 2 g h )1/2

= ( 2 × 9.8 × 2.5 )1/2

= 7 m/s

At the bottom of swing, if the vine breaks, then he is moving with horizontal velocity 7 m/s in gravitational field.  

If vertical distance from ground to bottom of swing is 5 m, then time t for Tarzan to reach ground is given by

S = (1/2)g t2 or   t = (2S/g)1/2

= ( 2 × 5 / 9.8 )1/2

= 1.01 s

Horizontal distance traveled by Tarzan = 1.01 × 7

= 7.07 m
