Our physics teacher just asked this question in class. And I'm pretty sure it is possible.Acceleration is given by the formula v-u/t.
But if the sum (v-u) is not zero then acceleration cannot be zero!
Please, I need detailed answers.Just the example won't do.

I've read that when in the process of making home made ice cream we use salt to lower the temperature of the ice. I understand it lowers the temperature of the ice sunstantially.
My Question:
Will salt water or brine freeze in a home freezer?

Will it reach a lower temperature?....and would that ice melt more slowly at room temperature than ice made of pure water?

A car of mass 1000 kg is being towed on level ground by a van of mass 2000 kg. There are constant retarding forces (due to air resistance and friction) on both the car and the van. The car force on the car is 300 N; on the van it is 500 N.

1) What is the size of the force due to the van's wheels that pushes the van forwards?

2) What is the size of the tension T in the towbar?

3) When the two vehicles are travelling at 15 m/s, the van driver disconnects the motor from the driving wheels, and the van and the car slow down at a constant rate due to the constant retarding forces acting on the vehicles. How far do the two vehicles travel before coming to rest?

Can u explain it so I understand it? Thanks!

Many theories which were once accepted as scientific truths were later refuted by subsequent ones or advances in technology. Do you think that this will happen in the future about something we accept as a truth today?
