At the instant the displacement of a 2.00 kg object relative to the origin is = (2.00 m) + (4.00 m) - (3.00 m) , its velocity is = - (5.85 m/s) + (2.10 m/s) + (8.31 m/s) and it is subject to a force = (9.47 N) - (6.28 N) + (6.46 N) . Find the acceleration of the object ((a), (b) and (c) for , and components respectively), the angular momentum of the object about the origin ((d), (e) and (f) for , and components respectively), the torque about the origin acting on the object ((g), (h) and (i) for , and components respectively), and (j) the angle between the velocity of the object and the force acting on the object.

On a hot saturday morning while people are working inside, the air conditioner keeps the temperature inside the building at 22degreesc. at noon the air conditioner is turned off, and the people go home. the temperature outside is a constant 33degreesc for the rest of the afternoon. if the time constant for the building is 4 hr, what will be the temperature inside the building at 4 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? at 6 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? when will the temperature inside the building reach 24degreesc? 324281

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 − t2)k (iv) r (t) = 2t j + (50 − t2)k (v) r (t) = (50 − 2t) i + 2t j + (50 − t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?
