Mechanics> projectile motion...
a ball is thrown at an angle theta to the ground,when the wind exerts a force mg on it,state with reasons whether it will be a parabola or not???if so state how will be its axis of symmetry???!
1 Answersmotion will be straight line y=x is the equation of its motion
prof
initial velocity of particle is ucos@i +usin@j
total accleration is a=-gi-gj
applying s(x,y)=ut+(at^2)/2
xi+yj= (ucos@i+usin@j)t +-(gi+gj)t^2/2
x=ucos@t-gt^2/2.....1 , y=usin@t-gt^2/2.......2
x-y=(ucos@-usin@)t........3
putting 3 in 1 or 2 we get (x-y)=0 and tan@=y/x
we get the eq of path as straight line

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
