You are in a car that is traveling along highway 99 at a constant speed of 22 m/s.
Suddenly you see a truck also traveling at a constant speed (3.0 m/s) that is on a track to cross your lane from an alley on the right and is moving into your lane
(which you can’t get out of, because of broader safety concerns like head on traffic in the other lane). Your car’s maximum acceleration is 6.0 m/s2 (either way, getting faster or slower) and your reaction time of 0.50 s between first seeing the truck and applying the brake or the accelerator. The distance from the side street, where you first notice the truck, to the right edge of your lane is 2.0 m and the lane also has a constant width of 4.0m, check for yourself that all these numbers are reasonable.
The width of a car is 2m, the truck is 3.0 m wide.
You obviously want to stop before hitting the truck. Let’s visualize the situation:
a) Draw a picture of the situation (half a page is a good size).
b) Draw a motion diagram for the car from the moment you see the truck.
c) Draw the a-t, v-t, and x-t diagram for the car from the moment you see the truck.
please focus on graphs.
The floors of a 15 storey building are spaced 3,2m apart. On ground level a man and a woman get into the lift. They go up to the 15th storey. When they go down, the woman gets off on the 5th floor and the man returns to the ground floor. What is the distance traveled by the man?
Lucy Lightfood stands with one foot on one bathroom scale and ther othe foot on a second bathroom scale. Each scale reads 350N. What is Lucy's weight?
Calculate the speed of light in glycerol if the index of refraction for glycerol is 1.470.
From Van Buren Bridge I cycle straight east along Hwy34 for 7.2 miles. I turn left into
Looney Lane and ride straight north for 2.0 miles where I reach the LBCC campus.
Along Hwy34, the traffic is sometimes terrifying. A few years ago the new bike path
was built, and I tried it out. I did not take Hwy34 but followed the new safe route that
was suggested by friends. So I rode the 3.1 miles on the new bike path from the
VanBuren/Harrison Bridge along Hwy34 east, then north east along Riverside Dr.,
SW Queen Ave. and finally along Hwy99E to LBCC. It was a Saturday, and I was
30min late to the TASS session at LBCC. That was not what I had planned, and I am
back riding along Hwy34 with my heart fearfully beating but being in time for class.
On my rides I often think about how another bike path could create a better and safer
riding experience.
a) Assume the community would agree to build a necessary bike path in a straight
line from the intersection of Hwy34 and Riverside Dr. to the LBCC campus.
What would be the distance of that bike ride?
Super Mario is standing on a 4.0 m tall mushroom. When he jumps off of it, what will his velocity be right as he is about to hit the ground?
A hydrocarbon contains 7.7% by mass of hydrogen and 92.3% by mass of carbon the relative molar mass of the compound is 78, derive the emperical formular of the compound. Name the hydrocarbons and write it's structural formular (H=1, C=12)
You are launching water balloons at a rival team using a large slingshot. The other team is set up on the opposite side of a flat‐topped building that is 30.0 ft tall and 50.0 ft wide. Your reconnaissance team has reported that the opposition is set up 10.0 m from the wall of the building. Your balloon launcher is calibrated for launch speeds that can reach as high as 115 mph at angles between 0 and 85.0° from the horizontal. Since a direct shot is not possible (the opposing team is on the opposite side of the building), you plan to splash the other team by making a balloon explode on the ground near them. If your launcher is located 55.0 m from the building (opposite side as the opposing team), what should your launch velocity be ((a) magnitude and (b) direction) to land a balloon 5.0 meters beyond the opposing team with maximum impact (i.e. maximum vertical speed)?
An electron in a uniform electric and magnetic field has a velocity of 1.20 104 m/s (in the positive x direction) and an acceleration of 2.00 1012 m/s2 (in the positive z direction). If the electric field has a magnitude of 20.0 N/C (in the positive z direction), what can you determine about the magnetic field in the region? What can you not determine
. An electron is accelerated through 2 400 V from rest and then enters a uniform 1.70-T magnetic field. What are (a) the maximum and (b) the minimum values of the magnetic force this particle can experience?
