Unformatted text preview: 1110 (8th ed.) The acceleration of point A is defined by the relation: a = 1.08 sin kt – 1.44 cos kt where a and t are expressed in m/s2 and seconds, respectively, and k = 3 rad/s. Knowing that x = 0.16 m and v = 0.36 m/s when t = 0, determine the velocity and position of point A when t = 0.5 s.
Problem is unit specific!!! 11.27. The acceleration of slider A is defined by the relation: a = − 2k k − v
2 2 where a and v are expressed in m/s2 and m/s, respectively, and k is a constant. The system starts at time t = 0 with x = 0.5 m and v = 0. Knowing that x = 0.4 m when t = 0.2 s, determine the value of k. ...
