Answer:
6.32 m/s 18.43° northeast
Explanation:
We express the velocity of hawk as:
We consider positive x towards east and positive y due north. So the magnitude is simply the square root of the square components:
≈
And the angle with respect to the east should be with:
Answer:
B
Explanation:
the reason the small turtle has more momentum is because it was less an example is I have two rocks a rock that weighs 1 oz and another rock that weighs half a pound the one that is half a pound Falls faster in the one that weighs an ounce Falls last hopefully that makes sense
The PDR is a thick volume that commonly used to provide guidance for prescription drugs available in the United states. The PDR is the most commonly used drug reference . The information is the same as the leaflet found in the drug package also known as the package insert. Drug companies pay to have their drugs included, so many generic medicines will not be found in the book.
For over 60 years, physicians and researchers have turned to PDR for the latest word on prescription drugs. It includes comprehensive and up-to-date information on more than 4000 FDA approved drugs.
Answer:
The answer is A
Explanation:
Work done = mgh
where mass, m = 92kg, g= 9.81, height,h= 325m
Therefore,
W= mgh
W=92*9.81*325
W=293319
W=2.93*10>5
(A) The total initial momentum of the system is
(1.30 kg) (27.0 m/s) + (23.0 kg) (0 m/s) = 35.1 kg•m/s
(B) Momentum is conserved, so that the total momentum of the system after the collision is
35.1 kg•m/s = (1.30 kg + 23.0 kg) <em>v</em>
where <em>v</em> is the speed of the combined blocks. Solving for <em>v</em> gives
<em>v</em> = (35.1 kg•m/s) / (24.3 kg) ≈ 1.44 m/s
(C) The kinetic energy of the system after the collision is
1/2 (1.30 kg + 23.0 kg) (1.44 m/s)² ≈ 25.4 J
and before the collision, it is
1/2 (1.30 kg) (27.0 m/s)² ≈ 474 J
so that the change in kinetic energy is
∆<em>K</em> = 25.4 J - 474 J ≈ -449 J
