An particle is moving in xy - plane with a constant speed v_(0) such that its y displacement is given by y=alphae^-(2v_(x)/(sqrt3v_(0))), where v_(x) is component of velocity along the x - axis. If at some instant x component of it velocity is positive and the slope of the tangent on its path is -(1)/(sqrt3) , then the displacement of the particle in y - direction at the instant is

Projectile motion is a combination of two one-dimensional motion: one in horizontal and other in vertical direction. Motion in 2D means in a plane. Necessary condition for 2D motion is that the velocity vector is coplanar to the acceleration vector. In case of projectile motion, the angle between velocity and acceleration will be 0^@ltthetalt180^@ . During the projectile motion, the horizontal component of velocity ramains unchanged but the vertical component of velocity is time dependent. Now answer the following questions: A particle is projected from the origin in the x-y plane. The acceleration of particle in negative y-direction is alpha . If equation of path of the particle is y = ax - bx^2 , then initial velocity of the particle is

Can the direction of motion of a body change if its velocity is changing at uniform rate ?
