The unit associated with amplitude is hertz true or false

I can certainly think of a graph of a wave-like quantity (like maybe the frequency deviation of an FM-modulated carrier) where the amplitude of the graph would have the units of Hertz. But then, I've been an Electrical Engineer for almost 50 years, and that would be overthinking it.

For YOUR purposes, here on , the far-better choice is FALSE.

car stops. he keeps going = he has inertia

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer
