The car moves such that its speed uniformly increases with time from 50 kph at Position 0, to 80 kph at Position Q, during 10 seconds. The radius of curvature of the hump at Position O is 40 m. At Position P is the transition from the hump to the dip where it was reached at 4 seconds from Position 0. If the car maintains a constant magnitude of the total acceleration from the hump to the dip, Calculate (a) the magnitudes of the tangential and normal components of the car's acceleration at Position P, and (b) the radius of curvature at Position Q. Neglect the geometry of the car.

At t = 0 a truck starts from rest at x = 0 and speeds up in thepositive x-direction on a straight road with acceleration aT. At the sametime, t = 0, a car is at x = 0 and traveling in the positive x-direction withspeed vC. The car has a constant negative x-acceleration: acarx = -aC,where aC is a positive quantity. (a) At what time does the truck pass thecar? (b) At what x-coordinate does the truck pass the car?
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.

a) A flywheel with a diameter of 356 mm accelerates uniformly from rest at a rate of 2.5 rad/s² for a period of 1.8 minute. It then continues at the maximum speed attained for a further period of 4.5 minutes, after which it decelerates uniformly to rest over a final period of 2.8 minutes. Calculate for the flywheel: (a) The maximum angular velocity attained in rad/s and also in rev/min. (b) The rate of deceleration during the final period of the motion. (c) The angle, given in radians, turned through by the flywheel during its period of acceleration.
