A particle is acted upon by constant magnitude force perpendicular to it which is always perpendicular to velocity of particle. The motion is taking place in a plane it follows that:

A particle of mass 120g moving at speed of 750cm/s is acted upon by a variable forrenpposite to its direction of motion as shown in figure. If the velocity of the particle becomes 250cm/s along the direction of force, fund the value of time't' for which force acted.
