A car starts from a state of rest and drives along a level, straight road. For the first 30 s, the car speeds up with a constant acceleration of 2.50 m/s2, after which it continues at the constant velocity that it has acquired for the next 5.00 minutes, at which time the brakes are applied, and there is an acceleration of -2.2 m/s2 until the car stops. What is the total displacement of the car from its starting point, and the total time of travel?

5. A cyclist rides 8.0 km east for 20 minutes, then he turns and heads west for 8 minutes and 3.2 km. Finally, he rides east for 16 km, which takes 40 minutes. (a) What is the final displacement of the cyclist? (b) What is his average velocity?
Light-rail passenger trains that provide transportation within and between cities speed up and slow down with a nearly constant (and quite modest) acceleration. A train travels through a congested part of town at 5.0 m/s. Once free of this area, it speeds up to 12 m/s in 8.0 s. At the edge of town, the driver again accelerates, with the same acceleration, for another 16 s to reach a higher cruising speed. What is the final speed?

A car, initially at rest, accelerates at a constant rate, 3.36 m/s2 for 32.6 seconds in a straight line. At this time, the car decelerates at a constant rate of -2.00 m/s2, eventually coming to rest. How much distance (in meters) did the car travel during the deceleration portion of the trip?
A car has an initial velocity of 17.8 m/s (SOUTH). The car has an unknown acceleration for a time of 7.11 seconds, at which point the car has a final velocity of 4.20 m/s (NORTH). During this time what is the car's displacement?
A car starts from rest, then accelerates at a constant rate over a distance of 80 m. It then immediately decelerates at a constant rate over a distance of 136 m. The entire trip lasts a total duration of 26.0 s. What were the magnitudes of the cars accelerations for the speedup and slowdown stages respectively?
Traumatic brain injury such as concussion results when the head undergoes a very large acceleration. Generally, an acceleration less than 800 m/s2 lasting for any length of time will not cause injury, whereas an acceleration greater than 1000 m/s2 lasting for at least 1 ms will cause injury. Suppose a small child rolls off a bed that is 0.36 m above the floor. If the floor is hardwood, the child's head is brought to rest in approximately 2.2 mm. If the floor is carpeted, this stopping distance is increased to about 1.2 cm. Calculate the magnitude and duration of the deceleration in both cases, to determine the risk of injury. Assume that the child remains horizontal during the fall to the floor. Note that a more complicated fall could result in a head velocity greater or less than the speed you calculate. Hardwood floor magnitude m/s2 duration ms Carpeted floor magnitude m/s2 duration ms

A train is initially travelling along a straight track at a steady speed of 30 m s¯¹. At time t = 0.00 s a signal ahead turns red. It takes the driver 0.60 s to react and apply the brakes. Once the brakes are hit, the train decelerates with a constant acceleration of magnitude 9.0 m s2 until it comes to rest. What is the total distance travelled by the train in the period between the signal turning to red and the train coming to rest? Give your answer by entering a number (correct to an appropriate number of significant figures) in the empty box below. Total distance travelled = m.
Light-rail passenger trains that provide transportation within and between cities speed up and slow down with a nearly constant (and quite modest) acceleration. A train travels through a congested part of town at 5.0 m/sm/s . Once free of this area, it speeds up to 11 m/sm/s in 8.0 ss. At the edge of town, the driver again accelerates, with the same acceleration, for another 16 ss to reach a higher cruising speed. What is the final speed?
A blue car travels down a straight road at a constant speed of 19.1 m/s. As they pass a red car, initially stopped on the side of the road, the red car speeds up at a rate of 2.02 m/s2. How much distance (in m) does the red car travel before it overtakes the blue car?
