For each of the motions described below, determine the algebraic
sign (positive, negative, or zero) of the x component and y
component of velocity of the object at the time specified. For all
of the motions, the positive x axis points to the right and the
positive y axis points upward.

To develop the ability to break a frame or machine down into subsystems and to determine the forces developed at internal pin connections Part D A tractor shovel Frames and machines are systems of pin-connected, multiforce members. Frames are designed to support loads, whereas machines are designed to transmiltl o alter the effects of loads. For a frame or machine to be in equiibrium, each member of the trame or machine system must be in equilibrium. Free-body diagrams of the...
20125982 ANALYZE (A) Determine how the velocity varles for positive acceleration and initial velocity to the right. The acceleration vs. time plot for constant acceleration is a straight line parallel to the time axls. It lles above the origin for acceleratlon to the right. During the acceleration, the velocity Increases by 1.6 m/s each second, so the velocity vs. time graph is a line with a slope of 1.6 m/s per second, and X m/s )+1.6 m/s2)t. The car starts...

Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....
For your Project, you will develop a simple battleship game. Battleship is a guessing game for two players. It is played on four grids. Two grids (one for each player) are used to mark each players' fleets of ships (including battleships). The locations of the fleet (these first two grids) are concealed from the other player so that they do not know the locations of the opponent’s ships. Players alternate turns by ‘firing torpedoes’ at the other player's ships. The...
