The centre of gravity of a triangle is at the point where three

The forces which meet at one point and have their lines of action in different planes are called

At a given instant ship A is travelling at 6 km/h due east and ship B is travelling at 8 km/h due north. The velocity of B relative to A is

The equation of motion of a particle starting from rest along a straight line is x = t^{3}  3t^{2} + 5. The ratio of the accelerations after 5 sec and 3 sec will be

The locus of the instantaneous centre of a moving rigid body, is

A projectile is thrown at an angle a to the horizontal with Î± velocity v. It will have the maximum centripetal acceleration

The c.g. of the shaded area of the below figure whose curve OM is a parabola from yaxis, is

If a body moves in such a way that its velocity increases by equal amount in equal intervals of time, it is said to be moving with

. If the gravitational accelerational at any place is doubled, the weight of a body, will
