Concept explainers

Displacement, Velocity and Acceleration

In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.

Linear Displacement

The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

2. A child running around in a field has the following position and velocity at time t = 0: x = 1.5 m, y = 2.0 m Vx = -3.5 m/s, vy=-1.0 m/s At time t = 2.5 s, it has the following position and velocity: x = -2.0 m, y = 1.5 m vx = -0.50 m/s, v, = 2.0 m/s Using this information, find the child's average velocity and average acceleration during that time interval. Write your answers in unit vector notation.
At a soccer practice, the players run sprints. They start at the goal, run 10 m toward the center of the field and then run back to the goal. Then they run 20 m toward the center of the field and back to the goal. Finally they run 30 m toward the center of the field, turn around, and run back to the goal again. One player times herself to try and beat her personal best time. She runs the first 10 m in 2.5 s and gets back to the goal in 2.8 s. Then she runs the 20-m sprint in 5.7 s and gets back to the goal in 6.7 s. She runs the final 30-m sprint in 12 s and gets back to the goal in 15 s. Define the positive direction as forward, toward the center of the field and consider what a position versus time graph of her motion would look like. Rank the sprints according to their slopes on the position versus time graph, from steepest positive slope to steepest negative slope. Rank from steepest positive slope to steepest negative slope. To rank items as equivalent, overlap them.
The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 57 km/s. lo the crow's great surprisc, a Klingon ship is 150 km directly ahead, traveling in the same direction at a mere 21 km/s. Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 4 5s The Enterprise's computers react instantly to brake the ship. What magnitude acceleration does the Enterprise need to just barely avoid a collision with the Klingon ship? Assume the acceleration is constant Hint: Draw a position versus time graph showing the motions of both the Enterprise and the Klingon ship. Let æn - 0km be the location of the Interprise as it returns from warp drive I low do you show graphically the situation in which the collision is "barely avoided"?

1. Hendrix and Tacey were to compete in a race over a course 2km long. Tacey crawls straight and steadily at its maximum speed of 0.4m/s toward the finish line. Hendrix runs at its maximum speed of 10m/s towards the goal for 1.7km and then stops to tease Tacey. How close to the goal can Hendrix let Tacey approach before resuming the race, which Tacey wins in a photo finish? Assume that when moving, both contestants move steadily at their respective maximum speeds.

1) A man flies a small airplane from Fargo to Bismarck, North Dakota—a distance of 180 mi. Because he is flying into a head wind, the trip takes him 2 h. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1 h 15 min. What is his speed in still air, and how fast is the wind blowing? a. what is the speed (mph) in still air? b. wind speed (mph)? 2)A boat on a river travels downstream between two points, 60 mi apart, in 1 h. The return trip against the current takes 2 1/2 hours. a. What is the boat's speed (in still water)? b. How fast does the current river flow?
Question 3 of 3: Rocky McBlock is a receiver for the Kennesaw Kilowatts in Metro Metric Football League. In this league all distances on the field are measured in meters, and Rocky always runs straight up and down the field (there is no sideways motion - only motion towards and away from the end zone). Rocky leaves the line of scrimmage when the ball is snapped and runs forward for 18 meters at a speed of 9 seconds. He catches the ball and continues to run forward for 16 more meters in 12 seconds, at which point he reaches the end zone. What is his speed before he catches the ball? What is his speed after he catches the ball? What is his average speed for the whole play from the time he leaves the line of scrimmage until the time he reaches the end zone?

Car A was traveling east at high speed when it collided at point O with car B , which was traveling north at 45 mi/h. Car C , which was traveling west at 60 mi/h, was 32 ft east and 10 ft north of point O at the time of the collision. Because the pavement was wet, the driver of car C could not prevent his car from sliding into the other two cars, and the three cars, stuck together, kept sliding until they hit the utility pole p. Knowing that the weights of cars A, B, and C are, respectively, 3000 lb, 2600 lb, and 2400 lb, and neglecting the forces exerted on the cars by the wet pavement, solve the problems indicated.Knowing that the coordinates of the utility pole are xp= 46 ft and yp = 59 ft, determine (a) the time elapsed from the first collision to the stop at P,(b) the speed of car A.
