That depends on what you're calling the 'x-component'.
As you increase the launch angle of a projectile, the vertical component
of its initial velocity increases, and the horizontal component of its initial
velocity decreases.
At the same time, the vertical component of its acceleration is a constant
9.8 m/s² throughout the event, while the horizontal component of its
acceleration is a constant zero.
Answer:
Boy has the greater linear velocity.
Explanation:
The liner velocity in a rotatory system is defined as:
v = ω×r
where,
v is the liner velocity
ω is the angular velocity
r is the radius.
The boy is near the edge and the girl is closer to the center. The scenario is shown in the image below.
As, mentioned in question, they are turning out at a constant rate, so the angular velocities of both the boy and the girl are same.
<u>From the above inference, it can be concluded that now the linear velocity only depends on the radius of the disc. The linear velocity is directly proportional to the distance from the center.</u>
Thus, the greater the distance from the center, the greater the value of liner velocity.
<u>From the question also and from the image also the distance of the boy from the center is greater than the distance of the girl from the center. </u><u>That's why boy has greater linear velocity. </u>
<u>Answer:</u>
A) Mass of dinosaur = 77,000 kg
Weight of dinosaur = 755370 N
B) Mass of dinosaur = 77,000 kg
Weight of dinosaur = 377685 N
<u>Explanation:</u>
A) Mass of dinosaur the brachiosaurus = 77,000 kg
We have weight of body = mg = 77,000*9.81 = 755370 N
B) Mass of a body is constant, it will not get affected by change in acceleration due to gravity value.
So, Mass of dinosaur = 77,000 kg
We have weight of body = mg' = m*g/2 = 77,000*9.81/2 = 377685 N
