Kinetic energy, KE = 0.5 mv^2
Where m is the mass
V is the velcocity
First calculate the kinetic energy of the bullet
Ke = 0.5(0.008 kg) ( 370 m/s)^2
Ke = 547.6 J
547.6 J = 0.5( 74 kg) v^2
<span>V = 3.85 m/s</span>
684,000. This should give you the correct answer as the 4 is the thousands place. Good luck :D
Answer:
you use the distance formula: square root of (x2-x1)^2 + (y2-y1)^2. it is a little hard to type the equation out so I reccomend you look up the distance formula and plug the given coordinates into it
