A particle is moving along X -axis with 4m/s. in front of plane mirror which is moving along , negative direction with [2m/s .Speed of image , with respect to ground will be:

The acceleration of a particle moving along x-axis is given by a = 6t. Initially it has a velocity of 4m//s along negative x-direction and it is at the origin. When will it return to the origin (in sec.)?

For a particle moving along the x-axis, mark the correct statement(s).

A particle moves perpendicular towards a plane mirror with a constant speed of 4 cm//s .What is the speed of the image observed by an observed moving with 2 cm//s along the same direction? Mirror is also moving with a speed of 10cm//s in the opposite direction. (All speeds are with respect to ground frame of refrence)

Comprehension # 5 One particle of mass 1 kg is moving along positive x-axis with velocity 3 m//s . Another particle of mass 2 kg is moving along y-axis with 6 m//s . At time t = 0, 1 kg mass is at (3m, 0) and 2 kg at (0, 9m), x - y plane is the horizontal plane. (Surface is smooth for question 1 and rough for question 2 and 3) The centre of mass of the two particles is moving in a straight line which equation is :-

An observer moves towards a plane mirror with a speed of 2(m)/(sec) . The speed of the image with respect to the observer is

Comprehension # 5 One particle of mass 1 kg is moving along positive x-axis with velocity 3 m//s . Another particle of mass 2 kg is moving along y-axis with 6 m//s . At time t = 0, 1 kg mass is at (3m, 0) and 2 kg at (0, 9m), x - y plane is the horizontal plane. (Surface is smooth for question 1 and rough for question 2 and 3) Co-ordinates of centre of mass where it will stop finally are :-

Two particles are moving along x-axis. Particle-1 starts from x=-10 m with velocity 4 m//s along negative x-direction and acceleration 2 m//s^2 along positive x-direction. Particle-2 starts from x=+2 m with velocity 6 m//s along positive x-direction and acceleration 2 m//s^2 along negative x-direction. (a) Find the time when they collide. (b) Find the x-coordinates where they collide. Both start simultaneously.
