A particle is moving along a straight line according to the law S = 3 ut - 5 at 2 where a > 0. Find the greatest and least velocities of the particle. => 3 u , 0..

Consider a system of N particles of masses m 1 , m 2 , m 3 ,------------ m N . Let a, b, c, . represent the particle numbers ranging from 1 to . Let the particle a be acted upon by some external force and by an internal force from every other particle..

Summary - The centre of mass is an imaginary point where one can assume the entire mass of the given system or object to be positioned. Principle of conservation of linear momentum states that the linear momentum of a system remains constant if the external forces acting on the system add up to zer..

The distance 'S' on a straight line traveled by a particle in time t is given by S = 5 t - 2 t 3 . What is the maximum velocity of the particle? => -1 or - 5 or 5 or 7..

The displacement s of a particle moving on a straight line at any time t is given by s = 8 t 2 + 6 t + 5. Find the instantaneous velocity of the particle at t = 4, if it exists. => 8 or 70 or 6 or Does not exist..

The curved line in the figure represents the trajectory of a particle. Let the particle be at P at time t. The position of p with reference to origin O is given by . Let the particle be at Q at time (t + D t). The position of Q with reference to P is given..

The same formulae can be generalised for uniform motion in two dimensions in the following way These formulae are applicable only to a point object moving uniformly in a straight line in the given plane. Similarly, for uniform velocity, where v x and v y are ..

The distance travelled by a particle on a straight line in time t is given by s = 5 + 6 t - t 2 + 7 t 3 where s is in feet and t is in seconds. Find the velocity of the particle when the acceleration is zero. => 5 ft/sec or 6 ft/..

From (1) we get, which is the law of conservation of momentum. Generalising to n particles, The law of conservation of momentum states that the total vector sum of momenta of bodies, in an isolated system, along any straight line remains conserved a..

A particle is moving along a straight line so that at time t , its displacement S from a fixed point in the line is given by S = 4 α sin(7 β t + γ) where α , β , γ are constants. If V and f are the velocity..
