A toy train rolling on a straight stretch of tracks, initially going 0.31 m/s slows uniformly to 0.14 m/s in 17 s. It then speeds up with a constant acceleration of magnitude 0.068 m/s2 over a distance of 4.2 m. iii) What was the total time for all this (slowing down and then speeding up)?

In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, with a maximum speed of 183.58 mi/h. The one-way course was 5.00 mi long. Acceleration rates are often described by the time it takes to reach 60.0 mi/h from rest. If this time was 4.00 s, and BL11t accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course?
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?
To pass a physical education class at a university, a student must run 1.0 mi in 12 min. After running for 10 min, she still has 500 yd to go. If her maximum acceleration is 0.15 m/s2, can she make it? If the answer is no, determine what acceleration she would need to be successful.
2. A car traveling in a straight line has a speed of -30.0 m/s at some instant. After 3.00 s, its speed is -20.0 m/s. What is its average acceleration in this time interval? What does the sign of the acceleration mean?
A toy train rolling on a straight stretch of tracks, initially going 0.31 m/s slows uniformly to 0.14 m/s in 17 s. It then speeds up with a constant acceleration of magnitude 0.068 m/s2 over a distance of 4.2 m. ii) What is its final speed after speeding up for the last 4.2 m
An express train passes through a station. It enters with an initial velocity of 23.6 m/s and decelerates at a rate of 0.16 m/s² as it goes through. The station is 200 m long. a) How long is the nose of the train in the station? b) How fast is it going when the nose leaves the station? 9.
5) An object falls from a building which is 1200 meters high. How long before it hits the ground if it has a constant acceleration of 9.8 m/s2 downward? 7) A boat moves at 1.5 m/s. It then accelerates at 2.40 m/s2. How fast is the boat moving 5.00 seconds after it started to accelerate?
3. A car is moving with constant speed of 80 km h' when suddenly the driver sees a cat 50 m straight ahead of the car. The driver's reaction time is 0.5 s and the maximum deceleration of the car is 10 m s2. a) Calculate the total distance travelled by the car from the moment the driver sees the cat until it stopped. What happens to the cat? b) Sketch acceleration against time graph to show the motion of the car.
A toy train rolling on a straight stretch of tracks, initially going 0.31 m/s slows uniformly to 0.14 m/s in 17 s. It then speeds up with a constant acceleration of magnitude 0.068 m/s2 over a distance of 4.2 m. i) How far does it go in the initial 14 s of slowing down?
b) A drunken motorist who is moving at a constant velocity of 25 ms' passes a stationary police patrol car. The patrol car immediately gives a chase at a constant acceleration and catches up with the motorist after a distance of 5 km. Calculate: i. the time taken by a patrol car to catch up with the motorist. ii. the acceleration of the patrol car.
Two hockey players are skating towards each other. They are 50.0 m apart. The first is accelerating from rest at 0.74 m/s2 and the second has already attained his maximum speed of 6.2 m/s. Find a) How long before they hit each other. b) How fast was the accelerating player going at the time of contact. c) How far has each player skated.
5. Your motion along the x-axis begins at rest and at x= 0. The motion consists of acceleration at 2.00 m/s2for 10.0 s, a time period of 6.00 seconds with no acceleration, and then deceleration at -1.00 m/s2for 20.0 s resulting in a final speed of zero. The total distance traveled is 420 m. What is the average speed during this motion? Give answer to 3 significant figures. Help solve this problem, thanks!
