Aman is marooned at rest on level frictionless ice. in desperation, he hurls his shoe to the right at 15 m/s. if the man weighs 720 n and the shoe weighs 4.0 n, the man moves to the left at ) 0b) 2.1 x 102 m/s. c) 8.3 x 102 m/s. d) 15 m/s. e) 2.7 x 10-3 m/s 19.

A 0.083 m/s approx 0

Explanation:

mass of the man is 720 N, the mass of the shoe is 4 N, and the man and the shoe were initially at rest. After throwing the shoe, the shoe had a velocity of 15 m/s. Using conservation of momentum:

since the man and the shoe were initially at rest, their initial momentum is zero

0 = M1V1 + M2V2 where M1 is the mass of the shoe ( 4 / 9.81), V1 is the velocity of the shoe 15m/s, M2 is mass of the man ( 720 / 9.81), V2 is the velocity of the man

MAKE V2 subject of the formula

- M1V1 = M2V2

- M1V1 / M2

substitute the values into the equation

- ((4/9.8) × 15) /( 720 / 9.81) = V2

V2 = - 0.0833 m/s approx 0  

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
