Answer:
102 kg.m/s
Explanation:
m = Mass of hammer = 12 kg
v = Final velocity = 8.5 m/s
u = Initial velocity = 0
t = Time taken = 8 ms
Force acting over a given amount of time or change in momentum is known as impulse.
Impulse
Impulse given to the nail is 102 kg.m/s
They may be changed because they may find evidence of some thing that will change their perspective on things.
The solution for this problem is:
Let u denote speed.
Equating momentum before and after collision:
= 0.060 * 40 = (1.5 + 0.060) u
= 2.4 = 1.56 u
= 2.4 / 1.56 = 1.56 u / 1.56
= 1.6 m / s is the answer for this question. This is the speed after the collision.
Ground water keept the ground at a stable level when it is gone the cavern it was in has no support and is at risk of callaps
The answer would be D. Because the iron fillings are attracted to the magnet underneath the glass.
