1) A pendulum is configured to have a period of 2 seconds. What is the length of the pendulum? (Use 10 m/s^2 for g)

If you doubled the length of the pendulum, what would its New Period be?

2) In a car collision, a car experiences a force for 1 seconds. The car’s mass is 700 kg and it was moving at 20 m/s before the collision and slowed down to 8 m/s.
What is the force on the car during the collision?

If the collision was with a 650 kg car that was at rest, what was the speed of the 650 kg car after the collision?

Two horizontal plates with infinite length and width are separated by a distance h in the z direction. the bottom plate is moving at a velocity u. the incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. align gravity with positive z. assume that the flow is fully-developed and laminar. if the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. sketch your system 2. identify the coordinate system to be used. 3. show your coordinates and origin point on the sketch. list all your assumptions. 5. apply the continuity equation to your system. nts of navier stokes equations of choice to your system 7. solve the resulting differential equation to obtain the velocity profile within the system make sure to list your boundary conditions. check units of velocity 8. describe the velocity profile you obtain using engineering terminology. sketch that on the same sketch you provided in (1). 9. obtain the equation that describes the volumetric flow rate in the system. check the units.

There are two routes similar in terrain; however, one route has an incline of approximately 28 degrees, and you must decide on which route to take. what is the maximum road grade that your fully loaded ecv can climb?
