two carts are at rest with a spring between them the spring is released find the mass of the cart on the right hand side

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

object 2 because all the other ones are wrong

the rearrangement of particles in a physical change. hope this

moisture is lackin, and organic acids are scarce.
