At time t = 0 s, a wheel has an angular displacement of zero radians and an angular velocity of +26 rad/s. the wheel has a constant acceleration of -0.43 rad/s2. in this situation, the time t (after t = 0 s), at which the kinetic energy of the wheel is twice the initial value, is closest

150s how do you solve for this? ? i keep getting a negative time value

t= 25.04 s

Explanation:

Given  that

Initial angular speed ,ωi= 26 rad/s

Angular acceleration ,α=0.43 rad/s²

We know that kinetic energy of the wheel given as

I=Mass monent of inertia

ω=Angular speed

If kinetic energy is two time then the final angular speed

We know that

t= 25.04 s

After 25.04 s then kinetic energy will become two times of the initial kinetic energy.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
