PA-4 (For Automobile Mechanics). One of the more well-known tests is crash testing. The car is timed and recorded going in two separate and opposite directions. The two times are averaged together to achieve the commonly accepted 0 to 60 time. Given this brief review, let us suppose that the velocity (in feet per second) of an automobile starting from rest is given by this model v = 80t/(t + 5). Determine the velocity and acceleration of the mobile when t=0, t=10, t=20, t=30, t=40, t=50, and t=60.

1) Most of us rode bikes a kid. Did you ever accidentally apply the front brake while riding down a hill and flip over your handlebars? Let's analyze the level of deceleration needed to cause this to happen (at this instant the normal force of the rear tire is zero). Assume the rider is moving down a hill at a constant velocity and att = 0, the rider squeezes the brakes and begins to decelerate. This action results in a force that points in the bi direction and passes through the contact points between the tires and the pavement. Be sure to include your FBD, IRD, and transformation array. b2 30 in. FB 13 in. 23 in.
