A `2 kg` object is slide along the frictionless floor with intial transverse volocity `(10 m//s) hat k` (a) Describe the motion (a) in car's frame and (b) in ground frame.

Explanation

(a) In car's frame (non-inertial)
`a_(x) = -5 m//s^(2)` (due to pseudo force)
`u_(x) = 0`
`a_(z) = 0`
`u_(z) = 10 m//s`
Non- apply, `v = u + at and s = s_(0) + ut + (1)/(2) at^(2)` in `x` and `z-` directions.
In ground frame (inertial)
`a_(x) = 0` ,`u_(x) = 0` and `u_(x) = 10 m//s`
