The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.00 s to a final velocity of 2.05 m/s, at which point the brakes are released. (a) What was its initial speed (in m/s), just before the brakes were applied? i have tried so many ways to solve this and i cant please explain
A race car is one lap behind the lead race car when the lead car has 47 laps to go in a race. If the speed of the lead car is 64 m/s, what must be the average speed of the second car to catch the lead car just before the end of the race (i.e., right at the finish line) in m/s? Assume 1 lap is 1.34 km.
A high-performance sports car can go from 0 to 100 mph (44.7 m/s) in 7.9s. a) What is the car's average acceleration? b) The same car can come to a complete stop from 30 m/s in about 3.2s. What is its average acceleration?
While driving down a straight road at 70.5 km/h, you pass your physics professor who happens to be out for a jog. He's running at a constant 4.00 m/s, and you decide to slow down and talk physics with him. If you apply your brakes exactly when you pass him on the road, and your car accelerates at 3.58 m/s2 during the breaking, how far do you end up going before he catches up to you?
Colonel John P. Stapp, USAF, participated in studying whether a jet pilot could survive emergency ejection. On March 19, 1954, he rode a rocket-propelled sled that moved down a track at a speed of 632 mi/h. He and the sled were safely brought to rest in 1.40 s (Fig. P2.41). Determine (a) the negative acceleration he experienced and (b) the distance he traveled during this negative acceleration.
A person lakes a trip, driving with a constant speed of 89.5 km/h, except, for a 22.0-min rest stop. If the persons average speed is 77.8 km/h, (a) how much time is spent on the trip and (b) how far does the person travel?
Professional Application Dr. John Paul Stapp was U.S. Air Force officer who studied the effects of extreme deceleration on the human body. On December 10, 1954, Stapp rode a rocket sled, accelerating from rest to a top speed of 282 m/s (1015 km/h) in 5.00 s, and was brought jarringly back to rest in only 1.40 s! Calculate his (a) acceleration and (b) deceleration. Express each in multiples of g (9.80 m/s2) by taking its ratio to the acceleration of gravity.
In World War II, there were several reported cases of airmen who jumped from their flaming airplanes with no parachute to escape certain death. Some fell about 20,000 feet (6000 m), and some of them survived, with few life-threatening injuries. For these lucky pilots, the tree branches and snow drifts on the ground allowed their deceleration to be relatively small. If we assume that a pilot's speed upon impact was 123 mph (54 m/s), then what was his deceleration? Assume that the trees and snow stopped him over a distance of 3.0 m.
A care package is dropped out of a cargo plane and lands in the forest. If we assume the care package speed on impact is 54 m/s (123 mph), then what is its acceleration? Assume the trees and snow stops it over a distance of 3.0 m.
In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, of 295.38 km/h. The one-way course was 8.00 km long. Acceleration rates are often described by the time it takes to reach 96.0 km/h from rest. If this time was 4.00 s and Burt accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course?
Give an example (but not one from the text) of a device used to measure time and identify what change in fiat device indicates a change in time.
A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 30.0 min at 80.0 km/h, 12.0 min at 100 km/h, and 45.0 min at 40.0 km/h and spends 15.0 min eating lunch and buying gas. (a) Determine the average speed for the trip. (b) Determine the distance between the initial and final cities along the route.
