A safety bumper is placed at the end of a racetrack to stop out of control cars. The bumper is designed such that the force that the bumper applies to the car is a function of velocity (v) and displacement (x) of the front edge of the bumper.
dv/dx = -Kv2(x + 1)3/dx
where K-30 s kg/m 5
m = 1500 kg
x varies from 0 to 3 meters
v(0) = 90 km/lh
Solve the ODE to calculate the velocity as a function of distance from the moment of impact (x-0) to full compression (x-3 m). Plot the results with appropriate axis labels.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
