Falling Flowerpot

--------------------------------------------------------------------------------

A 3 kg flowerpot drops from a tall building. The initial speed of the pot is zero, and you may neglect air resistance.

--------------------------------------------------------------------------------
a) What is the magnitude of the force acting on the pot while it is in the air 1.5 s after it begins to fall?
|F| = N *

--------------------------------------------------------------------------------
b) After the pot has fallen 26 m, what is its speed?
|v| = m/s *
sqrt(2*9.81*26) OK

HELP: Apply the appropriate formula from one-dimensional kinematics with constant acceleration.

--------------------------------------------------------------------------------
c) After the pot has fallen 26 m, it enters a viscous liquid, which brings it to rest over a distance of 1.5 m. Assuming constant deceleration over this distance, what is the magnitude of this deceleration?
|a| = m/s2 *
9.81*26/1.5 OK

--------------------------------------------------------------------------------
d) What is the force exerted on the liquid by the pot?
Ft = N

Need help with part d. Some guidance requested please!!!

A constant decceleration means a constant force is applied to it. Use F=ma to find the force the liquid exerts on the pot.
