Answer:
a. 20m/s
b.50N
c. Turkey has a larger mass than the ball. Neglible final acceleration and therefore remains stationery.
Explanation:
a. Given the force as 50N, times as 0.2seconds and the weight of the ball as 0.5 kg, it's final velocity can be calculated as:
Hence, the velocity of the ball after the kick is 20m/s
b.The force felt by the turkey:
#Applying Newton's 3rd Law of motion, opposite and equal reaction:
-The turkey felt a force of 50N but in the opposite direction to the same force felt by the ball.
c. Using the law of momentum conservation:
-Due to ther external forces exerted on the turkey, it remains stationery.
-The turkey has a larger mass than the ball. It will therefore have a negligible acceleration if any and thus remains stationery.
-Momentum is not conserved due to these external forces.
Since the bridge and all segments of it are static, the sum of the torques acting on any portion of the bridge you choose is zero for any pivot <span>point you may choose. See if you can find a rigid portion of the bridge and a wisely chosen pivot to which you can apply this powerful fact.
</span>Consider the triangular portion shown in bold and let x be the pivot. (This choice eliminates the torques
due to the tensions in the beams that attach at
point x.) Find the torques on this left hand
triangle (which can be considered a solid piece
because of the connections). Remember that
counterclockwise torque is positive. Assume
that the horizontal segment above is being
stretched, so that the force that the tension in
this segment exerts on the bold triangle is
directed to the right.
Express the torque in terms of T, L , and Fp.
Answer in terms of T and L :
Tt = (TL.sqrt 3) / 2
Summation Tx = -LFp - T sqrt[L^2 - (L/2)^2]
The negative value of the tension shows that the segment is actually under a compressible load. <span />
Answer:
<u>the autumnal equinox (when day and night are of equal length)</u>
<u>Explanation:</u>
The first event occurs around the 22nd or 23rd in the month of September. What usually happens is that regions around the Northern Hemisphere (which includes all of North America and Europe) experience an equal length of day and night.
While the second event occurs around March 20th or 21st mainly observable in countries found in the Southern Hemisphere.
Answer:
Federal Role in Education is primarily a State and local responsibility in the United States. It is States and communities, as well as public and private organizations of all kinds, that establish schools and colleges, develop curricula, and determine requirements for enrollment and graduation.
Explanation:
The Role of Public Education in Supporting American Democracy. Since the founding of public education in the United States, public schools have been charged not only with giving future workers skills for the private marketplace, but also with preparing students to be citizens in a democracy.
