At t=0 , a runner is moving forward at a speed of 7 m/s for 2 s the runner accelerates to the left at 0.5 m/s2 and backward at 1 m/s2 . find the runners final velocity in terms of the company directions (forward/back and left/right). what is the runners speed at t=2 (the length of the resultant of the perpendicular velocity components)? what is the runners position at t=2?

Which units can be used to measure length or distance? check all that apply. gram meter kilometer liter inch

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.

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?
