Use the worked example above to you solve this problem. a wheel rotates with a constant angular acceleration of 3.25 rad/s2. assume the angular speed of the wheel is 1.70 rad/s at ti = 0. (a) through what angle does the wheel rotate between t = 0 and t = 2.00 s? give your answer in radians and revolutions. rad rev (b) what is the angular speed of the wheel at t = 2.00 s? rad/s (c) what angular displacement (in revolutions) results while the angular speed found in part (b) doubles?

radiation warms things up temp rises convection currents air circ windy weather

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
