The uniform 100-kg beam is freely hinged about its upper end a and is initially at rest in the vertical position with theta = 0. determine the initial angular acceleration of the beam and the magnitude of the force fa supported by the pin at a due to the application of the force p = 300 n on the attached cable.

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s
