Question

2 football players of opposite team score live While We're trying to hit a ball on the ground and after colliding the move of together one with a mass of 60 kg was travelling with a velocity of 5 metre per second and the other footballer with a mass of 55 kg was moving faster with a velocity 6 metre per second towards the first player what is the direction and the velocity with which remove after they become entangled

Answer 1

Given, m1 = 60 kg

            u1 = 5m/s

           m2 = 55 kg

           u2 = - 6 m/s

Momentum of  two players before collision will be :

= 60 *  5  + 55  * - 6

= - 30 kg/m s     ---------------- (1)

Momentum of two players after collision with a velocity v will be ; 

= (m1 + m2) * v

= (60 + 55) kg * v m/s

= 115 v kg m/s       ----------------- (2)

On solving equation(1) and (2), we get

v = - 30/115 

  = - 0.26 m/s.

So, the velocity will be -0.26 m/s^-1 and the direction will be from right to left.


Hope this helps!

Answer 2

Answer:

Given, m1 = 60 kg

            u1 = 5m/s

           m2 = 55 kg

           u2 = - 6 m/s

Momentum of  two players before collision will be :

= 60 *  5  + 55  * - 6

= - 30 kg/m s     ---------------- (1)

Momentum of two players after collision with a velocity v will be ; 

= (m1 + m2) * v

= (60 + 55) kg * v m/s

= 115 v kg m/s       ----------------- (2)

On solving equation(1) and (2), we get

v = - 30/115 

  = - 0.26 m/s.

So, the velocity will be -0.26 m/s^-1 and the direction will be from right to left.
