Answer:
- Here we use the conservation of momentum theorem.
- m stands for mass, and v stands for velocity. The numbers refer to the respective objects.
- m1v1 + m2v2 = m1vf1 + m2vf2
- Since the equation is perfectly inelastic, the final velocity of both masses is the same. Let’s account for this in our formula.
- m1v1 + m2v2 = vf(m1 + m2)
<u>Let’s substitute in our givens.</u>
(0.002 kg)(700 m/s) + (5 kg)(0 m/s) = vf(0.002 kg + 5 kg)
I assume you are proficient in algebra I, so I will not include the steps to simplify this equation.
Note that I have considered the bullet’s velocity to be in the positive direction,
The answer is vf = 0.280 m/s

(17.36 micron/30sec) x (1x 10⁻⁶ meter/micron) x (1km/1,000 m) x (3600 sec/hr) =
(17.36 x 10⁻⁶ x 3600) / (30 x 1000) km/hr =
<em>0.000 002 083 km/hr</em>
Yes,it's true ok? So how have you been doing
