STATEMENT-1: Let DeltaABC be rigtht angle with vertices A(0,2),B(1,0)and C(0,0) if D is the point on AB such that the segment CD bisects angle C then the length of CD is (2sqrt2)/(3). STATEMENT-2: The number of points on the straight line which joins (-4,11) to (16,-1) whose co-ordinates are positve interger is 3. STATEMENT-3: If k=2 then the lines L_(1):2x+y-3=0,L_(2):5x+ky-3=0and L_(3):3x-y-2=0 are concurrent.

In one-dimensional kinematics, a particle can move strictly along a straight line. The description of motion of the particle can be done in two ways: (i) mathematical equation and (ii) graphs. The choice of a particular method for solving a problem often depends upon the type and nature of problem, for example the graphical method provides more physical insight One dimensional motion is categorised into 1. motion with constant velocity 2. motion with constant acceleration, and 3. accelerated and de-accelerated motion If you represent inotion (1) by the graph on position time and velocity-time coordinates, the graphs may look like as given below. One very interesting case comes up, when a particle is thrown at a certain angle from the horizontal, the particle travels in the medium along a curved path, known as parabola. - The trajectory of the parabola written in the mathematical equation is given by y=xtantheta-(1)/(2)(gx^(2))/((v_0costheta))^(2) Ineglect resistance of medium and its motion where Vs and are the initial velocity of the projectile and the projection angle at the point of projection measured with the + x axis. There are some applications which we have seen in our life, like in many game shows, the theory of the projectile is always used An air gun is aimed at an elevated target, which is released in a free fall by some mechanism as the bullet leaves the nozzle. Irrespective of falling speed of object, the bullet will always hit the target. QThe graph shows the psition of a hard ball with respect to time .The hard ball hits and rebounds on the hard surface .Ehich of the following graph represent the correct variation with repect to time?

Position (in m) of a particle moving on a straight line varies with time (in sec) as x=t^(3)//3-3t^(2)+8t+4 (m) . Consider the motion of the particle from t=0 to t=5 sec. S_(1) is the total distance travelled and S_(2) is the distance travelled during retardation. if s_(1)//s_(2)=((3alpha+2))/11 the find alpha .

Let the algebraic sum of the perpendicular distances from the points (2,0),(0,2) and (1,1) to a variable straight line be zero.Then the line pass through a fixed point whose coordinates are (1,1) b.(2,2) c.(3,3) d.(4,4)

A body travelling along a straight line traversed one third of the total distance with a velocity 4m/s. The remaining part of the distance was covered with a velocity 1 m/s for half the time and with velocity 3 m/s for the other half of time. The mean velocity averaged over the whole time of motion is :
