Please help. Thank you! A tired squirrel (mass of 1kg) does push-ups by applying a force to elevate its center-of-mass by 5cm. Determine the number of push-ups which a tired squirrel must do in order to do a mere 1.0 joule of work. If the tired squirrel does all this work in 4 seconds, then determine its power.

Arock collection comes from which part of earth?

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

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
