Study the vector diagram. Three vectors are drawn tail to tip method in the x y plane. Vector labeled T starts at the origin and is drawn in the northeast direction. The second vector is labeled U and drawn in the south south east direction. The third is labeled V and drawn in the north northeast direction. X and Y components are drawn for each vector along the x and y axis. Which formula can be used to find the x-component of the resultant vector? Tx - Ux - Vx Tx + Ux + Vx Tx = Tcosθ Tx = Tsinθ

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.

Suppose that 27 j of work is needed to stretch a spring from its natural length of 6 m to a length of 9 m. (a) how much work is needed to stretch the spring from 12 m to 14 m? j (b) how far beyond its natural length will a force of 78 n keep the spring stretched?

Two trains leave a station at the same time, train a travels at a constant speed of 16 m/s. train b starts at 8.0 m/s but accelerates constantly at 1.0 m/s squared. after 10.0 seconds, which train has the greater speed?
