Pls help this is due right now 1.) Landing with a speed of 79.6 m/s, and traveling due south, a jet comes to rest in 965 m. a.) Assuming the jet shows with constant acceleration, find the magnitude and direction of its acceleration. B.) to the south or to the north?

2.) a firefighter slides down a pole in a fire station with an acceleration of 8.2 m/s2. If the firefighter starts at rest and slides for a distance of 3.7 m , what is his final speed?

3.) a baseball player is dashing toward home plate with a speed of 3.0 m/s when she decides to hit the dirt. She slides for 1.5 s , just reaching the plate as she stops. A. What’s her acceleration? (Assume her running direction is the positive direction.) B. How far does she slide?

4.) when you see a traffic light turn red, you apply the brakes and stop with constant acceleration. If your initial speed was 28 m/s , what’s your average speed during braking?

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
