A body of mass 0.5kg is accelerated from rest and travels a distance of 40m in 2.5s. Determine,
i. The acceleration of the body.
ii. The net force applied on the body.
iii. Hence, or otherwise, determine change in momentum of the body

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

The heliocentric and the geocentric models of the solar system included these central principles

Which changes would result in a decrease in the gravitational force btween two objects? check all that apply
