Solve the all parts of given question:
Question: A 1000 kg weather rocket is launched straight up. The rocket motor provides a constant acceleration for 16 s, then the motor stops. The rocket altitude 20 s after launch is 6200 m. You can ignore any effects of air resistance.
Part I: What was the rocket's acceleration during the first 16s?
Part II: What is the rocket's speed as it passes through acloud 6200 m above the ground?
I want you to explain the physics in this question.
A 60kg pole vaulter running at 13m/s vaults over the bar. Her speed when she is above the bar is 0.7m/s. Neglect air resistance, as well as any energy absorbed by pole, and determine her altitude as she crosses the bar.
Assume after charging a 4.80 microF capacitor to 5 V you connect it to the second uncharged capacitor of 15 microF. What voltage will you voltmeter read across the second capacitor after repeating charge sharing process two times? State the answer..
The induced magnetic field at radial distance 6.7 mm from the central axis of a circular parallel-plate capacitor 2.0 x10-8 T. The plates have radius 4.1 mm. At what rate is the magnitude of the electric field among the plates changing?
A wire loop of radius 0/5 m has a resistance of 2.0 ohms. A uniform magnetic field perpendicular to the plane of the loop increases from 0 to 2.0T in .25 s What is the average current induced in the loop?
The speed of a bobsled is increasing because it has an acceleration of 2.1 m/s2. At a given instantin time, the forces resisting the motion, including kineticfriction and air resistance, total 450 N. The mass of the bobsledand its riders is 240 kg.
One proposal for dealing with radioactive waste is to shoot it into the sun. Calculate at what speed would it hit the sun

Estimate the minimum absolute pressure (in pascals) that can be developed at the inlet of a pump to avoid cavitation if the fluid is carbon tetrachloride at 20 celsius
In a certain region, the earth's magnetic field has a magnitudeof 5.1 x 10-5 T and is directed north at an angle of64° below the horizontal. An electrically charged bullet isfired north and 13° above the horizontal, with a speed of 630m/s. The magn..
A particle moves along the x-axis according to the equation x(t) = 2.0 + 3.0t2 - 1.0t3, where x is in meters and t is in seconds. What is its speed at that time
A 9.40kg projectile is fired vertically upward. Air drag decreases the mechanical energy of the projectile-Earth system by 69.5kJ throughout the projectile's ascent. How much higher would the projectile have gone were air drag negligible.
