Answer:
I believe he shouted eureka after he stepped into a bath and noticed that the water rose. He then realized that the volume of water displaced must be equal to the volume of the part of his body he had submerged
Explanation:
Answer:
The correct Answer to the question is : e) 4.1 m/s^2, 52 degrees north of east
Explanation:
F1= 68 N < 24º = 62.12 i + 27.65 j
F2= 32N < 132º = -21.41 i + 23.78 j
R= F1+F2= 40.71 i +51.43 j = 65.59 N < 51.63 º
By 2nd law of newton:
F= m * a
R= m*a
a= R/m
a= 4.1 m/s² < 52º (52 degrees north of east)
I consideer 0º at the EAST axis.
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
