A drag car starts from rest and moves down the racetrack with an acceleration defined by a= 50 - 10t, where a and t are in m/s2 and seconds, respectively. After reaching a speed of 125 m/s, a parachute is deployed to help slow down the dragster. Knowing that this deceleration is defined by the relationship a= - 0.02v2 , where v is the velocity in m/s, determine (a) the total time from the beginning of the race until the car slows back down to 10 m/s, (b) the total distance the car travels during this time.

A runner with a good awareness of her pace runs along a path of unknown length at a speed of 0.275 mi/min and then walks back to her starting point at a speed of 0.0500 mi/min. She neglects to note her time for each part of her path, but does measure the total round trip time to be 60.0 min. How far did she run? Do not include the walking distance
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.
A Nozomi Shinkansen train at rest travels from Osaka to Tokyo along a high-speed railroad track which makes a total of 3-hour journey, non-stop. From Osaka station, its distance x is given as a function of time t by the equation x(t)=−αt2+βt3 where α=4.35mihr2 and β=13mihr3. Determine:a) The average and instantaneous velocity of the train as it reaches Tokyo in mph.b) The average and instantaneous acceleration of the train as it reaches Tokyo in mihr2.
A spacecraft starts from rest, and makes a journey to a destination 447000 km from its starting point. It does so by accelerating at a constant rate of 9.82 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 9.82 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take?
A train is traveling down a straight track at 32 m/s when the engineer applies the brakes, resulting in an acceleration of −1.0 m/s2 as long as the train is in motion. How far does the train move during a 64-s time interval starting at the instant the brakes are applied in meters?
A car is moving with a velocity v(t)= 100-t2 in units of ft/sec where t is in seconds when the brakes are applied at t = 0. How far will the car travel before it comes to a stop, and what is its average velocity during that time?
Traveling with an initial speed of 70 kph, a car accelerates at 6000 km/hr2 along a straight road. How long will ittake to reach a speed of 120 kph? Also, through what distance does the car travel during this time?
A train is traveling down a straight track at 20 m/s when the engineer applies the brakes, resulting in an acceleration of −1.0 m/s2 as long as the train is in motion. How far does the train move during a 40-s time interval starting at the instant the brakes are applied?
The position of an object is given by x = at3 - bt2 + ct,where a = 4.1 m/s3, b = 2.2 m/s2, c = 1.7 m/s, and x and t are in SI units. What is the instantaneous acceleration of the object when t = 3.5 s?
A car is travelling at a constant speed of 100 km.hr at NLEX when the driver noticed that the bridge 10 m away is cut off. If the driver immediately applied the brakes upon noticing the cut off bridge, what must be his deceleration so he would not fall to the river?
A car is travelling at a constant speed of 100 km.hr at the highway when the driver noticed that the bridge 10 m away is cut off. If the driver immediately applied the brakes upon noticing the cut off bridge, what must be his deceleration so he would not fall to the river?
A commuter train travels between two downtown stations. Because the stations are only 1.00 km apart, the train never reaches its maximum possible cruising speed. During rush hour the engineer minimizes the time interval t between two stations by accelerating at a rate a1 = 0.100 m/s2 for a time interval t1 and then immediately braking with acceleration a2 = 0.500 m/s2 for a time interval t2. Find the minimum time interval of travel t and the time interval t1.
