Question

A particle passes through a point with position vector i+j when t=0 and moves with velocity 3i-2j. (A)it is accelerating. (B) its speed is constant. (C) its position vector at time t is 3i-j+t(i+j). (D) None

Answer 1

What will be the final velocity of a particle if its initial velocity =3i +4j and acceleration = 0.4i +0.3j after 10 s? A particle has initial velocity 2i+3j and initial acceleration -(3/4) i+(1/2) j. ... A particle is thrown in an upward direction with the initial velocity of 6om/s ...
