An object, starting from rest, rotates with an angular acceleration given by $\alpha = c + d t ^ { 2 }$ , where $\surd$ is in radians/s², t is in seconds, c = -3.0 rad/s² and d = 0.40 rad/s⁴. At t = 2.0 s the angular velocity of the object is A) -1.1 rad/s. B) 1.1 rad/s. C) -4.9 rad/s. D) -7.1 rad/s.

The Answer of An object, starting from rest, rotates with an angular acceleration given by $\alpha = c + d t ^ { 2 }$ , where $\surd$ is in radians/s², t is in seconds, c = -3.0 rad/s² and d = 0.40 rad/s⁴. At t = 2.0 s the angular velocity of the object is A) -1.1 rad/s. B) 1.1 rad/s. C) -4.9 rad/s. D) -7.1 rad/s.

An Object, Starting from Rest, Rotates with an Angular Acceleration α=c+dt2\alpha = c + d t ^ { 2 }α=c+dt2

An Object, Starting from Rest, Rotates with an Angular Acceleration $\alpha = c + d t ^ { 2 }$
