.

Find the magnitude and direction to the velocity of an object at any instant during the oblique projection of projectile.

A particle moves so that its position vectors varies with time as vecr=Acosomegathati+Asinomegathatj . Find the (a)Initial velocity of the particle (b)angle between the position vector and velocity of the particle atony time. ©Speed at any instant .

In the Fig. shown find relation between acceleration of wedge 1 and 2

Do you find any relation between pH and hardness of water?

A wooden wedge of mass 10 m has a smooth groove on its inclined surface. The groove is in shape of quarter of a circle of radius R = 0.55 m . The inclined face makes an angle theta =cos^(-1)((sqrt(11))/(5)) with the horizontal A block 'A' of mass m is palced at the top of the groove and given a gentle push so as to slide along the groove. There is no friction between the wedge and the horizontal ground on which it has been placed. Neglect width of the groove. (a) Find the magnitude of displacement of the wedge by the instant the block A reaches the bottom of the groove (b) Find the velocity of a wedge at the instant the block A reaches the bottom of the groove.
