A particle is projected towards the north with speed 20 m//s at an angle 45^(@) with horizontal. Ball gets horizontal acceleration of 7.5 m//s^(2) towards east due to wind. Range of ball (in meter) will be

A ball is projected from a point on a smooth horizontal floor at an angle theta with the horizontal . Speed of projection is u . Ball collides with the floor several times . Find the total time and horizontal distance covered by the ball .

A ball is projected from top of the table with initial speed u at an angle of inclination theta , motion of image of ball w.r.t ball

A ball is projected from top of the table with initial speed u at an angle of inclination theta , motion of image of ball w.r.t ball

A ball is projected from ground with a speed 70m//s at an angle 45^(@) with the vertical so that it strikes a vertical wall at horizontal distance (490)/(3)m from the point of projection. If the ball returns back to the poin tof projection without any collision with ground then find the coefficient of restitution between the ball and wall.
