Two people push on a boulder to try to move it. the mass of the boulder is 775 kg. one person pushes north with a force of 68 n. the other pushes west with a force of 43 n. predict the magnitude of the acceleration (in m/s2) of the boulder. assume that friction is negligible.

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.

Which of the following are not typically included in the periodic table? a. atomic mass b. element symbol c. isotopes d. number of electrons

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four
