Chapter 2: Problem 1

A displacement of magnitude \(32 \mathrm{cm}\) toward the east is followed by displacements of magnitude \(48 \mathrm{cm}\) to the east and then $64 \mathrm{cm}$ to the west. What is the total displacement?

Short Answer

Expert verified
Answer: The total displacement is 16cm toward the East.

Step by step solution

01

Identify the given displacements and their directions

We are given three displacements in the problem: 1. A displacement of \(32cm\) to the east 2. A displacement of \(48cm\) to the east 3. A displacement of \(64cm\) to the west
02

Simplify the problem by combining same-direction displacements

The first two displacements are in the same direction (east), so we can add their magnitudes together: \(\displaystyle 32cm + 48cm = 80cm\) to the east. Now, our problem is simplified to finding the total displacement after two displacements: 1. A displacement of \(80cm\) to the east 2. A displacement of \(64cm\) to the west
03

Calculate the net displacement

Now, we calculate the net displacement by subtracting the displacements in opposite directions: \(\displaystyle 80cm - 64cm = 16cm\). Since the eastward displacement (80 cm) is greater than the westward displacement (64 cm), the total displacement is toward the east.
04

Write the final answer

The total displacement is \(16cm\) toward the east.

In the problems, please assume the free-fall acceleration $g=9.80 \mathrm{m} / \mathrm{s}^{2}$ unless a more precise value is given in the problem statement. Ignore air resistance. At 3: 00 P.M., a bank robber is spotted driving north on I-15 at milepost $126 .\( His speed is \)112.0 \mathrm{mi} / \mathrm{h}$. At 3: 37 P.M., he is spotted at milepost 185 doing 105.0 milh. During this time interval, what are the bank robber's displacement, average velocity, and average acceleration? (Assume a straight highway.)

In the problems, please assume the free-fall acceleration \(g=9.80 \mathrm{m} / \mathrm{s}^{2}\) unless a more precise value is given in the problem statement. Ignore air resistance. While passing a slower car on the highway, you accelerate uniformly from \(17.4 \mathrm{m} / \mathrm{s}\) to \(27.3 \mathrm{m} / \mathrm{s}\) in a time of \(10.0 \mathrm{s} .\) (a) How far do you travel during this time? (b) What is your acceleration magnitude?
A relay race is run along a straight-line track of length \(300.0 \mathrm{m}\) running south to north. The first runner starts at the south end of the track and passes the baton to a teammate at the north end of the track. The second runner races back to the start line and passes the baton to a third runner who races \(100.0 \mathrm{m}\) northward to the finish line. The magnitudes of the average velocities of the first, second, and third runners during their parts of the race are \(7.30 \mathrm{m} / \mathrm{s}, 7.20 \mathrm{m} / \mathrm{s}\) and \(7.80 \mathrm{m} / \mathrm{s},\) respectively. What is the average velocity of the baton for the entire race? [Hint: You will need to find the time spent by each runner in completing her portion of the race.]
An airplane lands and starts down the runway with a southwest velocity of $55 \mathrm{m} / \mathrm{s}$. What constant acceleration allows it to come to a stop in \(1.0 \mathrm{km} ?\)
please assume the free-fall acceleration \(g=9.80 \mathrm{m} / \mathrm{s}^{2}\) unless a more precise value is given in the problem statement. Ignore air resistance. You drop a stone into a deep well and hear it hit the bottom 3.20 s later. This is the time it takes for the stone to fall to the bottom of the well, plus the time it takes for the sound of the stone hitting the bottom to reach you. Sound travels about \(343 \mathrm{m} / \mathrm{s}\) in air. How deep is the well?
