A superhero swings a magic hammer over her head in a horizontal plane. The end of the hammer moves around a circular path of rad

Korolek [52]

Answer:

9.21954 m/s

54 m/s²

Angle is zero

Explanation:

r = Radius of arm = 1.5 m

$\omega$ = Angular velocity = 6 rad/s

The horizontal component of speed is given by

$v_h=\omega r\\\Rightarrow v_h=6\times 1.5\\\Rightarrow v_h=9\ m/s$

The vertical component of speed is given by

$v_v=2\ m/s$

The resultant of the two components will give us the velocity of hammer with respect to the ground

$v=\sqrt{v_h^2+v_v^2}\\\Rightarrow v=\sqrt{9^2+2^2}\\\Rightarrow v=9.21954\ m/s$

The velocity of hammer relative to the ground is 9.21954 m/s

Acceleration in the vertical component is zero

Net acceleration is given by

$a_n=a_h=\omega^2r\\\Rightarrow a_n=6^2\times 1.5\\\Rightarrow a_n=54\ m/s^2$

Net acceleration is 54 m/s²

As the acceleration is towards the center the angle is zero.

Answer:

Option D.

Data; changing attitudes, beliefs, or values

Explanation:

When a speaker adds statistical data to prove the point, the audience's perception about things changes since the data implies that research has been conducted hence reliable. Consequently, the attitude of people and beliefs may change when such data is presented to them. Therefore, option D is correct.
