A car traveling at 25m/s slows down at a rate of -2.6 m/s2, what distance did it requiered to stop? a. 150m b. 120m c. 100m d. 50m
A car slows down at constant rate of 1.5m/s2 traveling 47 m until it comes to a complete stop. Calculate the initial speed of the car: A. 12m/s 70m/s 3m/s D. 47m/s E. 9.8m/s
5. An object is traveling at 20 m/s, but is accelerating at -5 m s2. After six seconds the object begins to slow and has come to a stop five seconds later. Draw graphs of position, velocity and acceleration versus time (each on separate axes) for this object. Be quantitative. Specify the position, velocity, acceleration and time tor point(s) when the object has stopped.
At time t = 0 a car has a velocity of 16 m/s. It slows down with an acceleration given by a = 0.50t, in m/s2 for t in seconds. At the end of 2.0 s it has traveled: A) 0 B) 12 m C) 14 m D) 34 m E) 33 m. The answer is E. I got D. Why is the answer E?
A driver traveling at 22 m/s slows down her 1500 kg car in order to not hit a brick wall. The distance between where she starts to brake and the wall is 75 meters. What is the average stopping force the driver experiences if she stops 5 meters before hitting the wall? (hint:the car takes 70 meters to stop, not 75) If the brake line bursts the driver decides to turn the in a wide arc parallel to the wall...
A car on a straight road first accelerates from rest to 20 m/s in 10 s, then travels at a constant velocity for 20 s, then slows down for 5 s and comes to stop. Find the total distance traveled by the car.
A 750 kg car slows to a stop from traveling southbound at 30 m/s over a distance of 500 m. What was the acceleration needed to stop the car? How large was the force required to stop the car? Two cables are being used to pull a 100 kg sled on a frictionless surface. The first cable has a tension of 500 N in a direction 15o south of east. The other cable has a tension of 800 N in...
A car traveling 70 km/h slows down at a constant 0.47 m/s2 just by "letting up on the gas." Calculate the distance it travels during the fifth second. Express your answer to two significant figures and include the appropriate units.
Consider a car moving in the positive direction with an initial velocity of 37 m/s slows down at a constant rate of -1.5 m/s2. What distance does the car cover in 10 seconds in meters?
consider a car moving in the positive direction with an initial velocity of 39m/s slows down at a constant rate of -0.5m/s square. the distance traveled by car is ____ m
