An object rotates about a fixed axis, and the angular position of a reference line on the object is given by 0 = 0.650e³t, where is in radians and t is in seconds. Consider a point on the object that is 5.00 cm from the axis of rotation. At t = 0, what are the magnitudes of the point's (a) tangential component of acceleration and (b) radial component of acceleration?

Hello, I need help with question 9 and the statement below. Please and thank you.

Proxima Centauri is part of the Alpha Centauri star system. It is the nearest star to the Solar system. Using the most advanced rocket technology we have available today, roughly how much time would it take to send a spaceship to Proxima and get back (round - trip time)? [Note: a "spaceship" is a spacecraft with a crew.] Choose the most correct answer; none of these are precisely correct. Group of answer choices 4.5 billion years 150,000 years 750 years 4.2 years 75 light - years 4.2 light-years
