4.Concerning freely fall body sport, the following parlance is correct BE()
A.In the 1 s, inside 2 ses, inside 3 ses ……of move of ratio is 1:3:5:……
B.At 1 s end, 2 s end, 3 s the ratio of speed of the end is 1:3:5< BRs>
C.In the 1 s, inside 2 ses and the ratio of the average speed in the 3 ses is 1:3:5< BRs>
D.Move it in two close together in the 1 seses bad is all 9.8 ms
5.The object is evenly do to decelerate straight line sport(sport direction constant), underneath the conclusion be correct BE()
The AN acceleration is more and more small
B.The acceleration is always contrary with the sport direction of object
C.Moving at any time is even to let up
D.Velocity is even to let up at any time
6.Two objects all do to evenly become to soon and straightly exercise, is give to settle of ? inside the time partition()
A.The acceleration is big, it move must also big ?
B.Early the speed be big, it move must also big ?
C.The end speed is big, it move must also big ?
D.Average the speed be big, it move must also big
7.The that the some quality order move with the variety relation in time for the s=10 ts ts-4ses 2, unit all and for the country border unit system unit, so it of early speed and acceleration BE() a ? respectively
A.10 ms/s, -the 4 ms/s 2 B.0s, -the 8 ms/s be 2 ?s
C.10 m/s, -8 m/s2 D.10 ms/s, 0 ?s
8.The car drives in the straight and even highway north bound by the speed of the 10 ms/s, start from the some time, the driver is with the a=4 ms/s 2 accelerations put on brakes and put on brakes to rise on the whole from the beginning automotive of when move a 12 ms, this process experience of time is()
A.3s B. 2s C. 2.5s D.1.5s
9.Is shown as diagram, a, the b means to successively be do with same early speed to evenly become to soon and straightly exercise from same location respectively of the v-t of two objects portrait, the following parlance then is correct BE()
The A.4 s end two object velocities be equal
The B.5 s end two object velocities be equal
The C.4 s end two objects meet
The D.5 s end two objects meet
The 9th diagram
10.The some object does to evenly accelerate straight line sport, if it exercise the average speed of whole distanceses be a v 1, the speed which exercises in the center and every moment is in the center and every momenta v 2, through whole distance half position of the speed be a v 3, then following relation in correct BE()
A. v1> v2> v3 B. v1= v2 v2= v3 D. v1

Two.Fill blank
11.The object of free whereabouts through A, B two point speed are 5 ms/ses and 10 ms/s respectively and take g=10 ms/s 2, A, the B order of height's being bad be a m, pass this road use of time be a s.
12.One object is evenly do with 2 ms/s 2 accelerations to accelerate straight line sport, the in the 2 ses move for the 12 ms, then the early speed of the object is.
13.If the diagram is a paper that"the measurement evenly becomes to soon and straightly exercise acceleration" gets in the experiment to take, order a beginning each 5 points to take 1 to count a point from the O, adhere to beat to order of successively and one by one in order weave to 1,2,3,4,5,6, measure s 1=1.22 cms, s 2=2.00 cms, s 3=2.78 cms, s 4=3.62 cms, s 5=4.40 cms,
s6=5.18cm.
(1)Close together two count some time partition of as s;
(2)The acceleration size of small car is a m/s 2;
(3)Beat some timer dozen counts to order 3:00 and the speed size of small car is a m/s.
Three.Solution(total 3, altogether 38 cent, distinguish to 12 cents, 12 cent, 14 cent.)
14.Gao Kong the top of the static balloon freely falls in one object from the 160 m, appurtenance body whereabouts the 2 s end open parachute evenly and soon whereabouts and ask object to totally experience to have another to fall a ground(the g take a 10 ms/s 2) with long hours
15.On the smooth horizontal plane, the quality orders from the 5 ms/s of the speed rightwards does to evenly and soon and straightly exercise.When quality point through an O order hereafter change to do to become to soon and straightly exercise.Henceforth it of the a-t diagram line is shown as diagram and pressed this regulation it to continuously exercise 0.5 mins, the which begs quality to order in this 0.5 mins moves with road.
The 15th diagram
16.Do evenly object of decelerate straight line sport, exercise after the 5 ses speed to let up to original half, and then know that the distance of sport in the last 2 ses is a 2 ms to beg:
(1)Object from decelerate stop time use;
(2)Decelerate athletic biggest distance;
(3)Acceleration and early speed of object sport.
