A car is driving along the freeway. Estimate the ratio ?r of its kinetic energy to its rest energy. No info is missing, unfortunately
2. The ratio between the kinetic energy of a particle and its rest mass energy is called the reduced kinetic energy of a particle. Find the expression which relates the radius of a proton synchrocyclotron to the reduced energy of the accelerated proton of maximum energy. Find the radius of a proton synchrocyclotron which works with a magnetic field of 2 Tesla and accelerates protons up to 650MeV?
Problem 2 (40%). While driving, some of a car's kinetic energy is lost to air drag. We would like to estimate the importance of air drag using dimensional analysis and the Buck- ingham a theorem. The relevant parameters are the drag force (FD), the frontal surface area (A) and velocity of the car (v), as well as the density of air (Pair = 1 kg/m3). Answer the following questions: 1. Derive the expression of the drag force as a function...
What kind of energy is a type of potential energy? Chemical Heat Kinetic Electrical If the sidewalk and cart dent one another too much, they accelerate toward one another. True False Consider the earth spinning from west to east on its axis. It is slowing down in its rotation due to friction with the air. Using the right hand rule, in what direction is the frictional torque? S pole to N pole N pole to S pole Counterclockwise along the...
UNUWE Special Characters Energy HW 4-Power Problem 5 (10 pts) While driving on the freeway, for a moment, you are stuck behind a slower car and can only travel at 24.6 m/s. When safe to do so, you change lanes and safely accelerate to a faster speed in only 3.9 s. Assuming the car has a mass of 4370kg and a power of 370 horsepower, what is your final velocity? 54 m/s Check Answer 70/80
Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next. When you increase your speed by 7.5 mi/h , the time to go one mile decreases by 13 s . What is your original speed?
Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next. When you increase your speed by 8.4 mi/h , the time to go one mile decreases by 14 s . What was your original speed?
A car sits in an entrance ramp to a freeway, waiting for abreak in the traffic. The driver sees a small gap between a van and an 18-wheel truck and accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 21.0 m/s when it reaches the end of the ramp, which has length 124 m . 1- What is the acceleration of the car?...
Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next. When you increase your speed by 7.9 mi/h , the time to go one mile decreases by 13 s What was your original speed? Express your answer using two significant figures.
A car sits in an entrance ramp to a freeway, waiting for a break in the traffic. The driver sees a small gap between a van and an 18- wheel truck and accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 25.0 m/s when it reaches the end of the ramp, which has length 111 m. Part A What is the acceleration of...
