Definately no more than 2 lbs a week any more and you are doing something wrong, like dehydrating yourself

In getting ready to slam-dunk the ball, a basketball player starts from rest and sprints to a speed of 5.45 m/s in 3.02 s. Assum
vova2212 [387]

Recall that average velocity <em>v</em> is given by

<em>v</em> = ∆<em>x</em>/∆<em>t</em>

where ∆<em>x</em> is displacement and ∆<em>t</em> is time.

Under constant acceleration, average velocity is also equal to the average of the initial and final velocities,

<em>v</em> = (<em>v</em>₂ + <em>v</em>₁)/2

The player starts at rest, so <em>v</em>₁ = 0, and speeds up to <em>v</em>₂ = 5.45 m/s in a matter of ∆<em>t</em> = 3.02 s. So

∆<em>x</em> = (<em>v</em>₂ + <em>v</em>₁) ∆<em>t</em> / 2

∆<em>x</em> = (5.45 m/s) * (3.02 s) / 2

∆<em>x</em> ≈ 8.23 m

During a __________ year period starting at about 4.5 billion years ago, bits and pieces of metal-rich particles, rocks, and ice
Greeley [361]

During a 30-10 million year period starting at about 4.5 billion years ago, bits and pieces of metal-rich particles, rocks, and ices accumulated to form the earth.

<h3>What is the Earth?</h3>

This is referred to as a type of planet which is habitable for different types of life forms. It is also the third planet from the sun and a majority of it contains water such as oceans etc.

Earth was formed billions of years ago through the bits and pieces of metal-rich particles, rocks, and ices which was in a 30-10 million year period which therefore makes it the correct choice.

A 2.9-kg cart is rolling across a frictionless, horizontal track toward a 1.4-kg cart that is held initially at rest. The carts
VikaD [51]

Answer:

The question is incomplete. I will assume you intend to find the total momentum of the two carts during collision. Therefore, we can use the conservation of momentum principle to get the total momentum at a certain instant before collision.

Explanation:

The conservation of momentum principle states that the initial net momentum of two bodies before collision is equal to the final net momentum after collision.

In this case, let's denote the rolling cart as <em>'a'</em> and the stationary cart as <em>'b'</em>.

Momentum, P = MaVa +MbVb

P=(2.9)(+4.7) + (1.4)(-1.9)\\P= 13.68 + (-2.66)\\P= 13.68-2.66\\P=+11.02 Kg.m/s

Therefore, the total momentum before collision is 11.02 Kg.m/s.
