Describe the motion of a ball being thrown straight up in the air in terms of kinetic and potential energy. as the ball rises up and balls back down, how is kinetic and potential energy affected? when is each type of energy the greatest and the least? what is true about the total mechanical energy of the ball?

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
