1) Imagine an object moving horizontally with uniform (that is, constant) velocity. Sketch the position time and velocity-time graphs for this motion.

2) Imagine tossing an object straight up into the air, then catching it. Sketch the position-time and velocity-time graphs for this motion, from the moment it leaves your hand to the moment just before it lands in your hand.

3) Imagine tossing a ball slightly upwards and towards another person. Consider the motion from the moment the ball leaves your hand to the moment just before it lands in the other person’s hands. Draw the trajectory for the ball. In how many dimensions is the object moving?

Expert Solution

ANS 1 -> The position time graph determines the change in position of the object. The speed of the object as well can be determined by using the line graph.

Here the time lies on the X- axis and position lies on the Y- axis

The position vs time graph for an object moving with uniform velocity in the horizontal direction is a straight line passing through the origin and having a positive slope.

The velocity vs time graph for an object with uniform velocity in the horizontal direction is a straight line parallel to the x axis.

ANS 2- > the position time graph for the object tossed straight up in the air and then catching it is a parabola, as shown below in the image.

The velocity time graph for an object tossed in the air and then catching it. Let us consider that the object is leaving the palm of the

Hand with 20 m/s velocitu and it goes straight up and it becomes zero velocity and then it comes back to the palm pf the hand with a velocity of -20 m/s. And all this happens in 4 seconds time.

The graph is given below.

ANS 3-> The trajectory that the ball follows is as below

The ball follow a parabolic path from one person to another person

As for the Dimensions in which the ball is mmoving.Theball is moving in Two Dimensions. The ball is in Two dimensional Motion.

If by any chance the ball starts moving sideways, i.e, left and right and three dimensional motion comes into play.

An object moving with uniform acceleration has a velocity of 10.0 cm/s in the positive x-direction when its x-coordinate is 2.73cm. If its x-coordinate 2.95 s later is −5.00 cm, what is its acceleration?

(c++) the constant velocity of an object moving in straight line is defined as r= d/t, where r is the speed, d is the distance and t is the time it takes to complete movement. write a program that will ask user to enter distance moved and the time needed to complete it. program should calculate speed of that object and print results on screen

1. Suppose the velocity of a moving object is given by the function f(t) = √ t for the time interval 0 ≤ t ≤ 2 sec. Approximate the total distance this object travels during this entire time interval with: (a) (4 pts) a Left-Hand Riemann sum using n = 4 rectangles. Write out the terms in the sum, but DO NOT evaluate it. (b) (4 pts) a Right-Hand Riemann sum using n = 6 rectangles. Write out the terms...

A sensor uses ultrasound to measure position and velocity of a moving cart in 1 dimension.

A sensor uses ultrasound to measure position and velocity of a moving cart in 1 dimension. It emits acoustic waves at 25 kHz and the speed of sound in air is 343 m/s. The maximum range of the cart from the wave emitter is 3 meters.A: If the sensor wants to measure distance position accurately to within 1cm of the cart, what is the maximum velocity the cart can have and not change position by more than 1cm while the...

A 4.00 g bullet is moving horizontally with a velocity of +355 m/s as shown in figure below. The bullet is approaching two blocks resting on a horizontal frictionless surface. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as shown in part (b). Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1150 g and its velocity is +0.550 m/s...

A 5.17-g bullet is moving horizontally with a velocity of +369 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the...
