A person pushing a stroller starts from rest, uniformly accelerating at a rate of 0.50 m/s2. What is the velocity of the stroller after it has travelled
9.0 m? (vf^2= vi^2+2aAx)
1 m/s
2 m/s
3 m/s
4 m/s

If the new moon happens on january 15th, what shape will it be on february 6th?

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.

Contrast the force of gravity between these pairs of objects: 1-kg mass and a 2-kg mass that are 1 m apart; a 1-kg mass and a 2-kg mass that are 2 m apart; and two 2=kg masses that are 1 m apart. i dont understand.
