Answer on Mechanics | Relativity Question for mia
104 kg, while not moving, is struck by a 4.2 g bullet moving with a speed of 835 m/s. If the
collision is elastic, find the speed that Superman had after the collision. (Assume the
bottoms of his superfeet are frictionless.)
V - speed of Superman after the collision.
Consider that the bullet stopped after the collision.
According to the law of conservation of linear momentum:
m1U = m2VV = U*m1/m2V = 835*0.0042/104 = 0.0337 m/s
So, the speed of Superman is 0.0337 m/s.
