A location of a particle is given in m by x, y and z coordinates as function of time in s as: x= -11+9t+11t^2 y= -23-21t z= -93+25t+11t^2 What is the magnitude of the objects acceleration at t= 3.00s? Would I add the second derivatives for magnitude?

I am convinced I have not received enough info to solve this prob. Please help me get started. A small steel ball bearing with a mass of 20.0 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.35 m. Calculated the...

I am trying to drop goods to a ridge of a mountain. The height from the ground to the plane is 203 m. The distance from the plane to the ridge is X. If plane is traveling at 65.278 m/s, how far in advance (horizontal distance) must the goods be dropped? -Should I calculate Vxo since Vyo would...
