A particle moves along a straight line and O is a fixed point on that line.the displacements irom U at given instants or time are snown in tne table.r (second)012345s (metre)Draw a displacement-time graph and find, over the interval of time from /=1to / =4.the average speed, ...
To find when the particle is at rest, you must set thev elocity function equal to 0 and solve for t. The velocity function is the first derivative of the position function. Remember to use the product rule on the position function in order to take the derivative correctly.x(t)=te^(...
FIELD: shipbuilding.;SUBSTANCE: invention relates to water transport and relates to control of ship movement by value of lateral displacements of its fore and stern points from current position of track line when it moves along given trajectory. Current position of the track line is defined as a...

A sports car moves along a horizontal straight road. At time / seconds the acceleration,in m s-2, is modelled using the differential equation(dv)/(dt)-2vt=t where v is the velocity of the car in m s-1.When / = 0, the car is travelling at 1 m s-1.Show that the velocity of...
lurch, pitch, shift - move abruptly; "The ship suddenly lurched to the left" jolt, jar - move or cause to move with a sudden jerky motion duck - to move (the head or body) quickly downwards or away; "Before he could duck, another stone struck him" bob - move up and down repeated...
2. To move or push along on wheels or rollers: rolled the plane out of the hangar. 3. To impel or send onward in a steady, swelling motion: The sea rolls its waves onto the sand. 4. To impart a swaying, rocking motion to: Heavy seas rolled the ship. 5. To turn around or part...
The soft “Oceanwings” made from sailcloth and mounted on Canopée enable the ship’s crew to adjust the height of the sails along the mast from the bridge of the ship, explains Christiaan De Beukelaer, author of “Trade Winds,” a book about the revival of sailing cargo ships, and ...
