A 85 kg lineman tackles a 90 kg receiver. The receiver is running 5.8 m/s, and the lineman is moving 4.1 m/s, at a right angle to the direction of the receiver's motion. If the lineman holds on to the receiver while they fall, what is their velocity immediately after the tackle

3.59 m/s

Explanation:

We are given that

Mass of lineman,m=85 kg

Mass of receiver,m'=90 kg

Speed of receiver,v'=5.8 m/s

Speed of lineman,v=4.1 m/s

We have to find the their velocity immediately after the tackle.

Initial momentum,

According to law of conservation of momentum

Initial momentum=Final momentum=

technology is the application of the knowledge gained by science.
