car was traveling at 33.0 m/s on a poorly lit country road.  The driver started to brake 0.35 seconds after he sees that a bridge is under construction 75 meters ahead.  The car slowed down uniformly.  What must be the minimum acceleration be to avoid crashing into the construction?

A VW Beetle goes from 0 to 54.0 mi/h with an acceleration of +2.35 m/s2. (a) How much time does it take for the Beetle to reach this speed? (b) A top-fuel dragster can go from 0 to 54.0 mi/h in 0.600 s. Find the acceleration (in m/s2) of the dragster.

The driver of a car traveling down the interstate slams on the brakes, causing the car to skid to rest over a distance of 152.4 m. If the car experienced an acceleration of -15.34 m/s2 during this time, how long did it take for the car to come to rest?

A roller coastre car rapidly picks up speed as it roles down a slope.  As it starts down the slope, its speed is 4 m/s.  But 3 seconds later, at the bottom of the slope, its speed is 22 m/s.  What is the average acceleration?

A Ferrari traveling well over the posted speed limit, passes a parked Tennessee State Trooper who decided to give chase. It takes the trooper 4.6 seconds to turn on the 'blue lights' and get the 'at rest' PW5000 powered Dodge interceptor moving. Then 8.3 seconds more to accelerate to its top speed and 63 seconds more to catch up with the speeder 3.5 km down the highway from the trooper's parking spot. Determine the average speed of the Ferrari over this distance in km/hr

A ball is thrown into a wall at a speed of 20 m/s and bounces off going 10 m/s in the opposite direction 0.2s after hitting the wall. What is the acceleration of the ball?

A car is 126 m from a stop sign and traveling toward the sign at 29 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?

A commuter backs her car out of her garage with a constant acceleration of 1.9 m/s2. Assume that her initial motion is in the positive direction.     How long does it take her to reach a speed of 2.35 m/s in seconds?  If she then brakes to a stop in 0.65 s, what is her acceleration in meters per square second?

At 5:11 p.m. in the highway and at the height of a town, a police patrol was traveling at a speed of 18.0 m / s towards the city, when the citizen's car approaches a speed of 94 mi / h towards the city.  After a reaction time of 0.800 seconds, the police start chasing the citizen with an acceleration of 5.00 m / s2.  Including the reaction time:  (a) How long does it take for the police patrol to reach the citizen?  (b) Indicate how far it reaches, from the moment the chase begins, and create a Position vs.  time graph, showing the two movements (that of the  citizen and the police patrol)

A VW Beetle goes from 0 to 42.0 mi/h with an acceleration of +2.35 m/s2. (a) How much time does it take for the Beetle to reach this speed? (b) A top-fuel dragster can go from 0 to 42.0 mi/h in 0.750 s. Find the acceleration (in m/s2) of the dragster.
