Okay, I got more problems that I need help with and I don't understand how to do this. 1. A small, spherical bead of mass 2:5 g is released from rest at t = 0 in a bottle of liquid shampoo. The differential equation of motion is dv/dt = g - (b/m)v The terminal speed is observed to be 2.6 cm/s.The acceleration of gravity is 9:8 m/s2. Find the value of the constant b in the integral form of the above equation v = (mg/b) ( 1 - e^(-bt/m)) Answer in units of Ns/m. 2. Find the time it takes to reach 0.53vt. Answer in units of s. 3. Find the value of the resistive force when the bead reaches terminal speed. Answer in units of N. #1-3 are all related 4. A high diver of mass 61.8 kg jumps of a board 10.4 m above the water. The acceleration of gravity is 9.8 m/s2. If his downward motion is stopped 4.22 s after he enters the water, what average upward force did the water exert on him? Answer in units of N.
