When a drag strip vehicle reaches a velocity of 9.8 * 10' m/s, it begins a negative acceleration by releasing a dragchute and applying its brakes. While reducing its velocity back to zero, its acceleration along a straight-line path isa constant -9.8 m/s². What displacement does it undergo during this deceleration period? answer in meters.

An unidentified flying object (UFO) is observed to travel a total distance of 19000 m, starting and ending at rest, over a duration of 4.23 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2.
The distance S that an object falls varies directly with the square of the time t. If an object falls 16 feet in one second, how long for it to fall 400 feet? The time required to drive a fixed distance varies inversely as the speed. It takes 1 hr at a speed of 400 km/h to drive a fixed distance. How long will it take to drive the same distance at a speed of 8 km/h?
We did this problem in class (3.10) and the answer ended up being 1.35 m/s but I'm still confused with the steps taken to get that answer.
An unidentified flying object (UFO) is observed to travel a total distance of 49000 m, starting and ending at rest, over a duration of 3.07 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2. 20,796 g s 10,398 g s 2,120 g s 1,060 g s
A student is testing the UAM equations by measuring the time it takes for light-weight plastic balls to fall to the floor from a height of 5 m in the lab. The student predicts the time to fall using g as 9.80 m/s^2 but finds the measured time to be 42.5% greater. Which of the following is the most likely cause of the large percent error? a. The acceleration due to gravity is 57.5% greater than 9.80 m/s^2 at this location. b. The acceleration due to gravity is 57.5% less than 9.80 m/s^2 at this location. c. Air resistance increases the downward acceleration. d. The acceleration of the plastic balls is not uniform. e. No Answer
In 1992, a 14-kg meteorite struck a car in Peekskill, NY, leaving a 20-cm-deep dent in the trunk. If the meteorite was moving at 500 m/s before striking the car, what was the magnitude of its acceleration while stopping? Find the time it takes for the meteorite to come to a complete stop.

In the vertical jump, an athlete starts from a crouch and jumps upward to reach as high as possible. Even the best athletes spend little more than 1.00 s in the air (their "hang time"). Treat the athlete as a particle and let ymax be his maximum height above the floor.To explain why he seems to hang in the air, calculate the ratio of the time he is above ymax/2 (moving up from ymax/2 to ymax and then moving down to ymax/2) to the time it takes him to go from the floor to that height. You may ignore air resistance.
In an 8.00 kmkm race, one runner runs at a steady 11.2 km/hkm/h and another runs at 14.9 km/hkm/h. How far from the finish line is the slower runner when the faster runner finishes the race? Express your answer in kilometers to three significant figures.
