A 89.3 kg fullback running east with a speed of 4.91 m/s is tackled by a 94.7 kg opponent running north with a speed of 2.98 m/s. (a) If the collision is perfectly inelastic, calculate the speed and direction of the players just after the tackle. ___m/s___° (north of east) (b)...

Why is more impulse delivered during a collision when bouncing occurs than during one when it doesn't?

A truck with a mass of 5750 kg traveling with a speed of 10 m/s collides at right angles with a car with a mass of 2500 kg traveling with a speed of 25 m/s. (a) Using the graphical method of vector addition, add the momentum vectors to get the total momentum of the system prior to...

how does this sound: The eggs shell does not break because of the rate of decelerates. When an egg hits a floor the egg comes to stop in a extremely short period of time. This creates a high average force on the egg. When a egg it the sheet it is taking a long time to come to rest and the...

so i muliply 1200 and 39700 to get the reaction force , that equals 47,640,000. Is that my answer

Two students hold an open bed sheet loosely by its corners to form a "catching net." The instructor asks a third student to throw an egg into the middle of the sheet as hard as possible. Why doesn't the egg's shell break? does this have to do with momentum? inertia? Newtons laws? so far my...

Calculate the force exerted on a rocket, given that the propelling gases are expelled at a rate of 1200 kg/s with a speed of 39700 m/s (at the moment of takeoff). DO i just multiply? do i have to take gravity into consideration?

A 9700 kg boxcar traveling at 18 m/s strikes a stationary second car. The two stick together and move off with a speed of 8.0 m/s. What is the mass of the second car? p=ma is 21825 m/s the answer? sig figs?
