AE 262 DYNAMICS 2010-2011 SPRING SEMESTER HOMEWORK#1 Given: 03.03.2011 Due: 15.03.2010 at 10:30 Submit to: Levent Ünlüsoy Q.1) Block C starts from rest and moves downward with a constant acceleration. Knowing that after 5 s the velocity of block A relative to block D is 2.4 m/s, determine (a) the acceleration of block C, (b) the acceleration of portion E of the cable. Q.2) A model rocket is launched from point A with an initial velocity v 0 of 86 m/s. If the rocket’s descent parachute does not deploy and the rocket lands 104 m from A, determine (a) the angle α that v 0 forms with the vertical, (b) the maximum height h reached by the rocket, (c) the duration of the flight.

Q.4) The rotation of rod OA about O is defined by the relation ϴ = 0.5e-0.8t sin 3π t, where ϴ and t are expressed in radians and seconds, respectively. Collar B slides along the rod so that its distance from O is r = 1 + 2t - 6t 2 + 8t 3 , where r and t are expressed in meter and seconds, respectively. When t = 0.5 s, determine (a) the velocity of the collar, (b) the acceleration of the collar, (c) the acceleration of the collar relative to the rod. Attention: 1.
