An alaskan rescue plane traveling 45 m/sdrops a package of emergency rations froma height of 145 m to a stranded party of reese (enr647) – homework 3, 2d motion 19-20 – dowd – (mcdanielmphy119203)3explorers. the acceleration of gravity is 9.8 m/s2.where does the package strike the groundrelative to the point directly below where it

package will strike at a distance of 244.7  m

Explanation:

Given data;

Velocity of plane 45 m/s

Acceleration due to gravity 9.8 m/s^2

horizontal component of plane velocity is ux = 45 m/s

vertical component is zero

in the same way

ay = - 9.8  m/s^2

ax = .0 m/s^2

motion in y direction = -145 m

from equation of motion time of flight is

solving for t  we get

t = 5.439 sec

Motion in x direction

s = 244.79 m

Therefore package will strike at a distance of 244.7  m

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
