In a two dimensional motion, instantaneous speed v0 is a positive constant. Then which of the following are necessarily true? a) the acceleration of the particle is zero b) the acceleration of the particle is bounded c) the acceleration of the particle is necessarily in the plane of motion d) the particle must be undergoing a uniform circular motion
Correct option is C) In a two dimensional motion, instantaneous speed v0 is a positive constant The width of the following are necessary- The acceleration of the Particle is necessarily in the plane of motion. This motion is two dimensional and given that instantaneous speed. Speed=v0 is positive constant. Acceleration is defined as the rate of change of velocity(instantaneous speed), hence it will also be in the plane of motion.
