ans isgiven as               y/x2=  U2sin@2-U!Sin@1/U2cos@2-u1cos@1

are lyophillic solutions irreversible or not !

as the work done by a const force in a closed pathis always zero,a const force is always conservative in nature.suppose a const force along 'x' is given by Fx=-6N.find the potential energy function associated with this force if U=0at  x=5

The path of the projectile as seen from another projectile,given u1,u2 and  @1,@2 are velocitiesand angles of projections

A 2kg block rests over a small hole in a table. a woman beneath the table shoots a 15gm bullet through yhe hole into the block,where it lodges how fast was the bullet going if the block rises 75cm above the table

may be! as up to 'U'

An ideal spring with constant K is hung from the ceilng and a block of mass M is attached too its lower end .the massis released with the spring  initially unstreched . then the maximum extension of the spring is

In a spring-mass system the length of the spring is L and it has a mass M attached to it and oscillates with angular velocity w .the spring is then cut into two parts,one(A) with relaxed length aL and other(B) with relaxed length(1-a)L.The force constants of the two springsAandB are

the velocity is doubled the ans is 16 perfect
