A 1.1 kg rubber ball is travelling at 2.0 m/s when it strikes a 3.9 kg rubber ball travelling at -1.9 m/s. If the 1.1 kg ball rebounds at a speed of -2.5 m/s, what is the new speed of the 3.9 kg ball?


Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm
