Hello there.
<span>0 + ½ m v(i)² - µ m g d = 0 + 0 </span>
Answer:
This question is vague because it doesn't specify whether 20° is the angle of incidence or the angle the ray makes with the surface
But If we consider 20° as the angle of Incidence...
The Angle of Reflection = 20° also
Because
From The Law of Reflection
Angle of Incidence = Angle of Reflection
Explanation:
Answer:
10.787 cm towards the 0.675 kg mass or 41.213 cm from the 1.65 kg mass.
Explanation:
= Mass of potato salad container = 1.65 kg
= Mass of lemonade container = 2.35 kg
= Mass of hot dog package = 0.675 kg
l = Length of basket = 52 cm
x = Location of lemonade container
When the mass is balanced along the center of mass the following equation applies
The lemonade container should be placed at 10.787 cm towards the 0.675 kg mass or 41.213 cm from the 1.65 kg mass.
Since direction is part of velocity, and the object is moving in a circle, its velocity is constantly changing.
Answer:
(a)
(b)
(c)
(d)
Explanation:
The linear momentum is defined as:
(1)
Where m is the mass and v is the velocity
<em>a.) </em><em>A proton with mass moving with a velocity of . </em>
Replacing those values in equation (1) it is gotten:
So, it has a linear momentum of
<em>b.)</em><em> A 1.6 g bullet moving with a speed of 374m/s to the right.</em>
Notice that in this case it is necessary to express the mass of the bullet in terms of kilograms:
⇒
<em>c.) </em><em>A 8 kg sprinter running with a velocity of 11.8 m/s. </em>
<em>d.) </em><em>Earth () moving with an orbital speed equal to 29700 m/s.</em>
