An object consists of a rectangular solid with rhos = 5.5 g/cm3, a rectangular thin plate with rhop = 10 g/cm2, and a thin wire with rhow = 58 g/cm. The object is symmetric about the yz plane. Determine the z position of the center of mass.

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

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1
