From the origin at the same time two points being to move. The first moves on the X-axis at a speed =4 m/s, and the second on the Y axis at a spe3ed of 3 m/ sec.

A rod of length 13 metres has one end P on the X-axis and the other end Q on the y-axis. If P moves on the X-axis with a speed of 12 m/sec, then the speed of the other end Q when it is 12 m from the origin is

A rod of length 13 metres. has its end P on the x-axis and the other end Q on the y-axis. If P moves along the x -axis with a speed of 12 m/sec, then the speed of the other end Q when it is 12 metres from the origin is

Two bodies start moving in the same straight line at the same instant of time from the same origin.The first body moves with a constant velocity of 40 m/s and the second starts from rest with a constant acceleration of 4m/s^2 . a)What is uniform speed? b)Find the time that elapses before the second catches the first body.

A force vecF=(4hati+5hatj)N acts on a particle moving in XY plane. Starting from origin, the particle first goes along x-axis to the point (5.0) m and then parallel to the Y-axis to the point (5,4 m. The total work done by the force on the particle is

Two persons A and B are standing at the origin and 210 meter away from the origin along the y-axis, respectively. A starts to move along x axis with acceleration 3.2 m//s^(2) and thereafter with the same retardation and comes to rest after moving 320 m B moves with a constant velocity and catches A in 15 s. The speed of B is (10n)/(3)m//s . Find the value of n.

A ball of mass 10 kg moving with a velocity 10sqrt3 m//s along the x-axis, hits another ball of mass 20 kg which is at rest. After the collision, first ball comes to rest while the second ball disintegrates into two equal pieces. One piece starts moving along y-axis with a speed of 10 m/s. The second piece starts moving at an angle of 30 with respect to the x-axis. The velocity of the ball moving at 30^@ with X-axis is x m/s. The configuration of pieces after collision is shown in the figure below. The value of x to the nearest integer is ______
