A Maxim machine gun fires 453 bullets per minute. Each bullet has a mass of 12g and a velocity of 660m/s.What the average force that the impact of these bullets exerts on a target? Assume the bullets penetrate the target and remain embedded in itCalculate answer to one decimal

A 4.00-kg model rocket is launched, shooting 50.0 g of burned fuel from its exhaust at an average velocity of 625 m/s.  What is the velocity of the rocket after the fuel has burned (ignore gravity and air resistance).

Starting with an initial speed of 5.00 m/s at a height of 0.357 m, a 2.82-kg ball swings downward and strikes a 4.70-kg ball that is at rest, as the drawing shows. (a) Using the principle of conservation of mechanical energy, find the speed of the 2.82-kg ball just before impact. (b) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 2.82-kg ball just after the collision. (c) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 4.70-kg ball just after the collision. (d) How high does the 2.82-kg ball swing after the collision, ignoring air resistance? (e) How high does the 4.70-kg ball swing after the collision, ignoring air resistance? (a) Number (b) Number (c) Number Mi i MI Units Units Units

A cue ball traveling at 6.57 m/s makes a glancing, elastic collision with a target ball of equal mass that is initially at rest. The cue ball is deflected so that it makes an angle of 30.0° with its original direction of travel. (a) Find the angle between the velocity vectors of the two balls after the collision.   (b) Find the speed of each ball after the collision.
