To visit your favorite ice cream shop, you must travel 470mwest on Main Street and then 980msouth on Division Street. Suppose you take 46sto complete the 470-mdisplacement and 73sto complete the 980-mdisplacement.What is the magnitude of your average velocity during this 119-second period of time?Express your answer to two significant figures and include appropriate units.

A fly is buzzing through the air at 0.1 m/d when a gust of wind comes and gives it an acceleration of 0.2 m/s^2 for 4.7 seconds. How far has the fly traveled during this time frame, being blown forward?

A “moving sidewalk” in an airport terminal moves at 1.0 m/s and is 35.0 m long. If a woman steps on at one end and walks at 1.5 m/s relative to the moving sidewalk, how much time does it take her to reach the opposite end if she walks (a) in the same direction the sidewalk is moving? (b) In the opposite direction?

An athlete crosses a 29 m wide river by swimming perpendicular to the water current at a speed of 1.1 m/s relative to the water. He reaches the opposite side at a distance 45 m downstream from his starting point. w = 29 md = 45 mvs = 1.1 m/s Part (a) How fast is the water in the river flowing with respect to the ground in m/s? Part (b) What is the speed of the swimmer with respect to a friend at rest on the ground in m/s?

The Moon is about 3.8 ✕ 108 m from Earth. Traveling at the speed of light, 3.0 ✕ 108 m/s, how long does it take a laser beam to go from Earth to the Moon and back again (in s)?

Hello, I had a physics question. "Just as the traffic light changes to green, a Mustang drives through the intersection at a constant velocity of 14.2 m/s [N]. A Camaro that was stopped at the light accelerates from rest at 2.9 m/s^2 [N]. How much time passes before the two cars meet again? How far have they travelled? I figured out how to do the question but I'm really confused on the units of the distance. I used the d = v/t formula and the vit + 1/2at^2 formula but the units I ended up getting were m^2/s^3 for distance when it should just be m.

suppose that Barbara’s velocity relative to Alex is a constant vBA = 52 km/h and car P is moving in the negative direction of the x axis. (a) If Alex measures a constant vPA=-78 km/h for car P, what velocity vPB will Barbara measure?

In his 1865 science fiction novel From the Earth to the Moon, Jules Verne described how three astronauts are shot to the Moon by means of a huge gun. According to Verne, the aluminum capsule containing the astronauts is accelerated by ignition of nitrocellulose to a speed of 11 km/s along the gun barrel’s length of 220 m. (a) In g units, what is the average acceleration of the capsule and astronauts in the gun barrel? (b) Is that acceleration tolerable or deadly to the astronauts? A modern version of such gun-launched spacecraft (although without passengers) has been proposed. In this modern version, called the SHARP (Super High Altitude Research Project) gun, ignition of methane and air shoves a piston along the gun’s tube, compressing hydrogen gas that then launches a rocket. During this launch, the rocket moves 3.5 km and reaches a speed of 7.0 km/s. Once launched, the rocket can be fired to gain additional speed. (c) In g units, what would be the average acceleration of the rocket…

The Moon is about 3.8 ✕ 108 m from Earth. Traveling at the speed of light, 3.0 ✕ 108 m/s, how long does it take a laser beam to go from Earth to the Moon and back again (in s)? The same physics was responsible for the noticeable delay in communications signals between lunar astronauts and controllers at the Houston Space Flight Center.

You encounter a moving walkway that is 81 m long and has a speed of 2.1 m/s relative to the ground.   How long would it take you to cover the 81 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.6 m/s relative to the walkway?   Express your answer using one significant figure.
