Answer:
22.22m/s
Explanation:
The momentum before a collision = momentum after collision so...
work out the momentum of the first object (the bullet)
its p = mv
0.04 kg × 300 m/s = 0.54 kg × v
rearrange this to find v which is 0.04 x 300 = 12
so 12 = 0.54 x v
12/0.5 = v
v = 22.22m/s
hope this helps!

Answer:
(a) The elevator has an acceleration of 2.14 m/s² and direction is downward
(b) The acceleration is a=2.14 m/s²
Explanation:
Let +y be upward direction
For Part (a)
The mass of student (whose weight is 550N) is:
ms=w/g
ms=550/9.8=56.1 kg
Apply ∑Fy=ma
Solve for acceleration a
The elevator has an acceleration of 2.14 m/s² and direction is downward
Part(b)
For the acceleration is the scale reads 670 N
For n=670N
So
