Atoy train is pushed forward and released at xi = 4.0 m with a speed of 2.5 m/s. it rolls at a steady speed for 2.0 s, then one wheel begins to stick. the train comes to a stop 7.7 m from the point at which it was released.
what is the train's acceleration after its wheel begins to stick?

Explanation:

Given

Initial speed u = 2.5 m/s

Final speed v = 0

Distance traveled S = 7.7 m

Duration t = 2.0 s

Solution

Distance traveled before the wheel got stuck

Distance traveled after wheel got stuck

Acceleration

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
