A linebacker with mass m1 = 90.0 kg running east at a speed v1 = 3.00 m/s tackles a fullback with mass m2 = 100. kg running north at a speed v2 = 5.00 m/s. The linebacker holds on to the fullback after the tackle, so that the collision is perfectly inelastic. The common speed of the players immediately after the tackle is closest to:

Expert Solution

Given:

Mass of the linebacker,

The linebacker is initially running east or in the positive x-direction.

Initial velocity of the linebacker is 3m/s east.

----------------

Mass of the fullback,

The fullback is initially running north or in the positive y-direction.

Initial velocity of the fullback is 5m/s north.

--------------

Find the common speed after the collision

----------------

Consider the collision

During collision momentum is conserved

Initial momentum = Final momentum

------------

Magnitude:

An object with mass m1= 3.00 kg is moving along the positive x-axis with a speed v1i=2 m/s straight towards two objects with masses m2= 2.00 kg and m3= 4.00 kg, which are initially at rest. When they collide, object 1 comes to rest and object 2 moves away with a speed of v2f=1.5 m/s at an angle of 50o from the incoming path of object 1. For everything that follows, use a coordinate system where the final path of...

A car with a mass of 1000 kg and a speed of v1 = 20.0 m/s approaches an intersection, as shown in the figure(Figure 1). A 1230 kg minivan traveling at v2 is heading for the same intersection. The car and minivan collide and stick together. The direction of the wreckage after the collision is θ = 44.0 ∘ above the x-axis. You may want to review(Pages 272 - 277). Part A: Find the initial speed of the minivan, assuming...
