Answer:
His performance would improve
Explanation:
This is because, he now has a larger distance to cover in the 10.0 ft diameter circle. This increased distance would cause him to give a greater angular speed to his whirl and thus a greater tangential velocity to the shot put. This greater speed would thus cause the shot put to travel more in the 10.0 ft diameter circle throw than in the 7 ft 6 in diameter circle throw.
Answer:
a)
b)
Explanation:
Given:
diameter of the table,
initial angular velocity of the table,
angular acceleration of the table,
a)
time of observation,
<u>Now the angular velocity after the given time:</u>
using equation of motion
where:
final angular velocity
b)
No. of revolutions made in the given time:
where:
initial revolution speed
Answer:
Explanation:
When the object fall from the top floor it moves with parabolic motion.
This particular case is a horizontal motion of a projectile, so the equation that relates the distance and the time in the y-axes is:
Here: y is the final height, it will be 0, because the object touch the ground.
y₀ is the initial height, it will be h and v₀ in y-axis is zero, because it has a horizontal initial velocity.
So we have:
(1)
We know that the velocity at the x-axes remains constant, then we have:
x is the distance from the base of the building
we can solve it for t and put on (1).
Solving it for x we will have:
But
