A crow is flying horizontally with a constant speed of 2.45 m/s when it releases a clam from its beak. The clam lands on the roc

ky beach 2.30 s later. Consider the moment just before the clam lands. (Neglect air resistance.). . a)What is its horizontal component of velocity? (in m/s). (b) What is its vertical component of velocity? (in m/s)

<span>Neglecting air resistance, the horizontal velocity will not have changed (i.e. it remains 2.45 m/s). The vertical velocity starts at 0 m/s and accelerates for 2.30 s (due to gravity). 9.8 = (x-0)/2.3 x = 22.54 Therefore your vertical velocity is 22.54 m/s.
</span>a) It would remain the same, because there is no force, and thus acceleration, in that direction. So, it would just be 2.45 m/s. b) Use<span>v=<span>v0</span>+at</span> Because <span>v0</span><span>=0 in the y direction, it is just v=at It said that t=2.3 s, and a=9.8. Plug that in... v=2.3*9.8=22.54 m/s</span>

I NEED HELP ASAP
LiRa [457]

The object is called a meteor because it is producing Streak of light  and has not yet struck earth.

<h3><u>Explanation:</u></h3>

A meteoroid is a celestial object which is very smaller than an asteroid. These objects are produced as a collision impact from mars or moon and float freely in space without any specific orbit. When they come inside the Earth's gravitational field, they are attracted by the Earth's gravity to Earth's crust. These objects in Earth's atmosphere are called meteors. As they travel through Earth's atmosphere, they do face a huge friction from Earth's atmosphere which let them burn and that is visible as the tail of the meteor.

Most of them are so small that they are burnt away in the atmosphere. But some are bigger and they reach the Earth's surface and are called as meteorites.

hi, Need help with triangle law of vector addition worksheet and a verifying Newtons second law worksheet?
Yuri [45]

Use Newton's second law and the free body diagram to determine the net force and acceleration of an object. In this unit, the forces acting on the object were always directed in one dimension.

The object may have been subjected to both horizontal and vertical forces but there was no single force directed both horizontally and vertically. Moreover, when free-body diagram analysis was performed, the net force was either horizontal or vertical, never both horizontal and vertical.

Times have changed and we are ready for situations involving two-dimensional forces. In this unit, we explore the effects of forces acting at an angle to the horizontal. This makes the force act in two dimensions, horizontal and vertical. In such situations, as always in situations involving one-dimensional network forces, Newton's second law applies.

Combine these three velocity vectors into a resultant: 3.0 m/s north, 4.0 m/s east 1.0 m/s west. Identify the resultant vector
Slav-nsk [51]

Answer:

The resultant vector is 1 m/s

Explanation:

The resultant vector is 1 m/s west based on triangle law of vector addition, when two sides of a triangle is represented by two vectors, the resultant vector is the third side of the triangle.
