(a) What net external force is exerted on a 1100.0-kg artillery shell fired from a battleship if the shell is accelerated at 2.40104m/s2 ? (b) What is the magnitude of the force exerted on the ship by the artillery shell, and why?
If the rocket sled shown in the previous problem starts with only one rocket burning, what is the magnitude of this acceleration? Assume that the mass of the system is 2.10103kg , the thrust Tis 2.40104N , and the force of friction opposing the motion is 650.0 N. (b) Why is the acceleration n one-fourth of what it is with all rockets burning?
What is the initial accelerationof a rocket that has a mass of 1.50×106 kg at takeoff, theengines of which produce a thrust of 2.00×106 N ? Do notneglect gravity. (b) What is unreasonable about the result?(This result has been unintentionally achieved by several realrockets.) (c) Which premise is unreasonable, or whichpremises are inconsistent? (You may find it useful to comparethis problem to the rocket problem earlier in this section.)

Upon arriving at work, Michael immediately kicks off a particularlyunfortunate day by hitting an employee with his 1200-kg car and breakingher pelvis. If it takes roughly 4,000 N to crack the average human pelvis,and Michael’s car came to a complete stop after 0.3 seconds ofdeceleration during the collision, how fast was he traveling in the parkinglot when he collided with his employee (let’s call her Meredith)? Assume allthe force of deceleration of his car was exerted on the Meredith’s pelvis,with none being exerted on brakes or opposed by friction (admittedlyunrealistic).

In an equation of elastic colistion, let's say there are two balls. Ball (A) is colliding into Ball (B) (Ball B is at rest). If Ball (A) Colides with Ball (B) and Ball (A) rebounds with it's original speed, how do I calculate/ what formula can I use to calculate the weight of Ball (B)? Also, what is a better defenition for Rebound in terms of Physics/ collision? (My apologies for the question at the end).
