A 1.04-kg binder is initially at rest on a wood desk. The binder is then pushed with a constant force of 4.2 N. Friction with a magnitude of 1.8 N is exerted on the moving binder by the surface of the desk. Draw an energy bar chart of the situation. Then determine the final velocity of the binder after it has been pushed 0.70 meters across the table.

How many seconds does it take a pebble released from rest off a bridge to fall 29.4 m ? what is the pebble's speed when it has fallen 29.4 m ?

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
