Question

In a two dimensional motion, instantaneous speed
vₒ 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

Answer 1

Answer:

In a two dimensional motion, instantaneous speed v

0

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=v

0

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.

hope this helps u dear
