how to find intial velocity when you are given distance and acceleration? can you give an example and answer?

While working on the digital effects for Star Wars XXIII, you find yourself responsible for a scene in which a TIE fighter (of mass m) crashes and embeds itself into a Star Destroyer (of mass 20m). To improve upon the scientific realism of the series, you decide to calculate the physics of the collision. Model the TIE fighter as a point particle and the Star Destroyer as a rod; assume that the fighter hits close to one end of the Destroyer and is traveling perpendicular to it at 500 m/s at the time of impact. You estimate that the Star Destroyer is 100 m long.

(a) What is the cruiser's final rate of rotation?

(b) At what speed does the cruiser's center of mass move after the collision?

a. A horizontal platform in the shape of a circular disk ( I = 1/2 MR²) rotates in a horizontal plane about a frictionless vertical axle. The platform has a mass M=200kg and a radius R=2.00 m. A student whose mass is m=60.0kg, walks slowly from the rim of the platform toward the center. If the angular speed of the system is 2.00 rad/s, when the student is at the rim, calculate the angular speed of the system when the student reaches the center.

b. A particle of mass 0.50 kg is moving with a velocity v=(6i+8j) m/s. Find the angular momentum L relative to the origin when the particle is at r=(2i+3k) m

High-voltage lines transmit needed power from energy providers to homes and
businesses, but exposure to the electric fields from power lines may have undesired
effects. Research and assess the effects of exposure to high-voltage lines on human
health.

Calculate the binding energy of the ²H nucleus and the ⁵⁶Fe nucleus.

Q/ If E is a macroscopic field inside the dielectric , and consider an atom at position R , Draw a sphere of radius ℓ ( Lorentz sphere) about R. suppose( l » a interatomic spacing ). The contribution to the microscope field at R from induced dipoles on other atoms can be divided in two parts ;

1. For atoms inside sphere
2. For atoms outside sphere

For the two cases prove that the local field at center of sphere is :

E_LF = E₀ – 4/3 πP + 4/3 πP + 0

How should one REALISE Classical and Quantum ACTION.(Please explain both)
That is,what in PERFECT sense is its Physical or Mathematical interpretetion + intuition + need + use + origin?!

Suppose that you are designing a parachute so that the terminal velocity using the parachute will be the same as the velocity at the end of a normal (frictionless) jump from a height of 2.80 m. If the parachute exerts a drag force of - b v where v is in meters per second and if the parachute is designed for an 70.0 kg person, what is b?

How is energy deposited in the interaction with matter of each of the following? photons, electrons, alphas, neutrons. Is the full energy of the radiation deposited? If not, where does the rest go? Is the energy deposited with high linear energy transfer or low linear energy transfer? Is the radiation track sparse or dense?

Make a long line of positive charges by placing them very close together. How does the field change as you move down the line of charges?

A pendulum is swinging in an elevator that is accelerating upward at a constant acceleration a. (a) Using the Lagrangian method, what is the equation of motion? Note be careful here, the velocity needs to be measured from an inertial reference frame. (b) What is the frequency of small oscillations?

When someone falls from a tall building, the most effective way to save him is to provide a net at the bottom so that the person slows down himself conveniently without hurting himself, the impulse here is same that would have been without the net but the net provides extra time for the change in momentum. Another example is, in the game of cricket when the ball is hit by the bat the time to change the momentum is expected to be the least by the batsman to get an excellent shot.

Support your claim using equations and provide two scenarios with numbers and calculations.

A sample of an unknown material appears to weigh 300 N in air and 222 N when totally immersed in alcohol. What are (a) the volume and (b) the density of the material? (c) What material is it?

Show what the expression E • J represents in field theory, what would its analogous expression be in circuit theory?
