A particle of mass is moving in a straight line with momentum p. Starting at time t= 0, a force F= kt acts in the same direction on the moving particle during time interval T so that its momentum changes from p to 3p. Here k is constant . The value of T is :
Kinetic energy of a particle moving in a straight line varies with time t as K = 4t^(2) . The force acting on the particle
A particle of mass m is moving along a circle of radius r with a time period T . Its angular momentum is
Kinetic energy of a particle moving in a straight line is proportional to the time t. The magnitude of the force acting on the particle is :
A particle P is moving along a straight line as shown in the figure. During the motion of the particle from A to B the angular momentum of the particle about O
A particle of mass 10 kg is moving in a straight line. If its displacement, x with time tis given by x=(t^(3)-2t-10)m then the force acting on it at the end of 4 seconds is
The displacement of a particle of mass 2kg moving in a straight line varies with times as x = (2t^(3)+2)m . Impulse of the force acting on the particle over a time interval between t = 0 and t = 1 s is
A particle with linear momentum of magnitude P is subjected to a force F = Kt ( K gt 0 ) which is directed along the direction of initial momentum. The time after which its linear momentum changes to 3P is
Force acting on a particle of mass m moving in straight line varies with the velocity of the particle as F=K//V K is constant then speed of the particle in time t
