Motion In Plane

Motion In Plane - Motion In 1D

An ant is moving in x-y plane with its position vector vecs=2t^2hati+5hatj then, velocity vector of it at t = 1 sec is:

The motion of a particle is defined by the position vector vec(r)=(cost)hat(i)+(sin t)hat(j) Where t is expressed in seconds. Determine the value of t for which positions vectors and velocity vector are perpendicular.

Motion In A Plane - Average Velocity Of Projectile Motion

Motion In A Plane - Projectile Motion

A particle moves in xy-plane. The position vector of particle at any time is vecr={(2t)hati+(2t^(2))hatj}m. The rate of change of theta at time t = 2 second. ( where 0 is the angle which its velocity vector makes with positive x-axis) is :

The velocity vector of the motion described by the position vector of a particle, r = 2t hati + t^(2) hatj is given by
