Answer:
4.53482 m/s
4.506 m/s
Explanation:
= Mass of player = 75 kg
= Initial velocity of player = 4.6 m/s
= Mass of ball = 0.47 kg
= Initial velocity of ball = 15 m/s
The linear momentum of the system is conserved
The player's speed is 4.53482 m/s
In the second case the equation of momentum is
The player's speed is 4.506 m/s
A command economy<span> is a system where the government, rather than the free market, determines what goods should be produced, how much should be produced and the price at which the goods are offered for sale.</span>
Answer:
a is the answer I think so
Momentum = mass x velocity = 91x9 = 819 kg-m/s.
