Answer:

For instance, an immobile object located at some height above the ground has potential energy. If the object starts to fall, its potential energy is converted to motion or kinetic energy. The heavier and the higher the object is, the more potential energy it will have. Transfer of thermal energy via conduction is aided by vigorously vibrating particles in a medium that has gained energy through heating.

A drum rotates around its central axis at an angular velocity of 19.8 rad/s. If the drum then slows at a constant rate of 3.02 r

Debora [2.8K]

a) Time taken =6.39 s

b) Angle of rotation while coming to rest = 188.17 rad

<u>Explanation:</u>

Initial angular velocity of the drum $\omega_{0} = 19.8 rad/s^{2}$

Angular acceleration of the drum $\alpha = -3.02 rad/s^{2}$

a.) We know that

$\omega =\omega_{0} + \alpha t$

$0 = 19.8 - 3.02 t$

$t = \frac{19.8}{3.02}$

$t = 6.39s$

b.) we know that

$\theta = \omega_{0} t + \frac{1}{2} \alpha t^{2}$

$\theta = 19.8 \times 6.39 + \frac{1}{2} \times 3.02 \times 6.39^{2}$

$\theta =188.17 rad$

A boy throws a ball straight up into the air. It reaches the highest point of its flight after 4 seconds.

Zanzabum

Answer:Take into account the the Earths gravity is 9.8 meters a second

Explanation:

Gravity pulls down on the ball at g=-9.81 m/s^2. Up is positive, down is negative.The ball started at a certain initial velocity of Vi m/s. Time it took is t=4s. Final velocity is Vf=0 m/s, because at the highest point the ball stops moving.

Vf=(g*t)+Vi

Rearrange for Vi.

Vi=Vf-(g*t)

Vi=0-(-9.81*4)=39.24 m/s (upward)

Think about it this way for the non-mathematical approach. The ball stops at the top. The initial velocity gets reduced by 9.81 m/s every second, and reaches 0 m/s at the top. It took 4 seconds, so 9.81*4 is equal to the initial upward velocity.
