The gap between two consecutive automobiles (distance between the back of a vehicle and the front of the following vehicle) is 65 . At a certain time, the front vehicle is traveling at 45 mi/h, and the following vehicle at 35 mi/h. If both vehicles start accelerating at the same time, determine the gap between the two vehicles after 15 sec., if the acceleration of the vehicles can be assumed as follows, where u, in the equation is vehicle speed in ft /sec. du 3.4-0.07u, (leading vehicle) dt du 3.3-0.065 dt = (following vehicle) ₂ 2
Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.70 m/s, and bumper car 2 is traveling 78.2° south of west at 4.20 m/s. They collide and stick together, as the driver of one car reaches out and grabs hold of the other driver. The two bumper cars move off together after the collision, and friction is negligible between the cars and the ground. W-O>E Car 2 Car 1 Vii (a) If the masses of bumper cars 1 and 2 are 596 kg and 625 kg respectively, what is the velocity of the bumper cars immediately after the collision? magnitude m/s direction ° east of south (b) What is the kinetic energy lost in the collision?
9/27/2011 Problem 6: Constant Acceleration Consider a bathtub on a luxury train. Before the train leaves the station, the bathtub is completely full. If the train has an acceleration of 12.8 ft/s², how much water will spill [ft³]? The dimensions of the bathtub are 5.0 ft long (i.e., in the direction of movement), 2.5 ft deep, and 3.0 ft wide.
The 19-Mg truck drives onto the 278-Mg barge from the dock at 25 km/h and brakes to stop on the deck. The barge is free to move in the water, which offers negligible resistance to motion at low speeds. Calculate the speed of the barge after the truck has come to rest on it. 25 km/h 278 Mg 19 Mg Answer: v = i km/h

Tests reveal that average drivers take about 0.75 s before they can react to asituation to avoid a collision. It takes about 3 s for a driver having 0.1% alcohol in their system todo the same. If such drivers are traveling on a straight road at 30 mph (44 ft/s) and their cars canaccelerate at -2 ft/s 2 (i.e., decelerate at 2 ft/s 2 ), determine the shortest stopping distance d for eachfrom the moment they see pedestrians
A driver on a level two-lane highway observes a truck completely blocking the highway. The driver was able to stop her vehicle only 10 ft from the truck. If the driver was driving at 70 mi/h, how far was she from the truck when she first observed it (assume perception-reaction time is 2.0 seconds)? How far was she from the truck at the moment the brakes were applied (use a/g=0.35)?
