Scientists are experimenting with a kind of gun that may eventually be used to fire payloads directly into orbit. In one test, this gun accelerates a 5.0 kg projectile from rest to a speed of 4.5*10^3 m/s. The acceleration of the projectile is 1.02x10^5 m/s2 . Determine the barrel length of this gun (the distance needed to get this projectile to this speed)

Scientists are experimenting with a kind of gun that may eventually be used to fire payloads directly into orbit. In one test, this gun accelerates a 2.7-kg projectile from rest to a speed of 2.0 × 103 m/s. The net force accelerating the projectile is 4.9 × 105 N. How much time is required for the projectile to come up to speed?

10) The velocity (t) of a particle as a function of time is given by (h) - 023 m/s) (4.1 m/s2)+- (62 m/s3)2. What is the average acceleration of the particle between t = 10 s and t - 205? A) - 15 m/s2 B ) 15 m/s2 C) -13 m/s2 D) O m/s2 E) 13 m/s2 11) A car starts from rest and accelerates uniformly at 3.0 ms2 toward the north. A second car starts from rest 60 s...
Solve exactly if possible. Express all decimals to 4 significant figures. 1) 2) 3) 4) 5) 6) 7) What are Newton's Laws of motion? What is a "frame of reference"? What is a coordinate system? Express the point x-3, y-4 using polar coordinates. What is the SI unit for force? How is it defined using SI base units? What are the four fundamental forces in the universe? What is the approximate gravitational acceleration, g, near the Earth's surface? If this...
please show work when possible so that I may better
understand. Thank you.
x=L The rail gun consists of two thick conducting rails connected to a power supply and there is a magnetic field assumed to be uniform and constant in the direction shown. A short conducting bar that is to be (or carry) the projectile is placed across the bars at x -0. The current flows through the bars as shown. The magnetic force on the bar causes it...
What are the Solutions to Part B of Chapter 2 of Tillery Physics 9th edition.......kinda pointless for you guys to only have the solutions that the book has already. 1. What was the average speed in km/h of a car that travels 400.0 km in 4.5 h? 2. What was the average speed in km/h of a boat that moves 15.0 km across a lake in 45 min? 3. How much would a 80.0 kg person weigh (a) on Mars,...
1. A pole is held vertically by attaching wires at a height of 13.4 m above the ground. The other end of each wire is anchored in the ground at a distance of 9.54 m from the base of the pole. The pole makes a right angle with the ground. What is the length of each wire? 2. A bug crawls 2.25 m along the base of a wall. Upon reaching a corner, the bug's direction of travel changes from...
These questions concern a space station, consisting of a long
thin uniform rod of mass 4.3 x 10^6 kg and length 769 meters, with
two identical uniform hollow spheres, each of mass 1.7 x 10^6 kg
and radius 218 meters, attached at the ends of the rod, as shown
below. Please note that none of the diagrams shown is drawn to
scale.
A. Suppose that the station starts out at rest (not rotating).
What we want is to get it...
PLEASE SHOW WORK AND ANSWER ALL PARTS. WHEN I ASKED THE
SECTIONS SEPARATELY THE ANSWERS DID NOT MATCH, THANK
YOU!!!

Question 1 1 pts What is the kinetic energy of a man who weighs 980N who is riding in a car traveling 40 km per hour? Express your answer in Joules, but don't type the unit in the answer box. Round to the nearest whole number. (Careful with the units) 1 pts Astudent slides her 80.0-kg desk across the level floor of her dormitory room a distance 4.00 m at constant speed. If the coefficient of kinetic friction between the...
