How long does a player sit out of a game of handball for committing a second or third foul?
yulyashka [42]

Answer:

Walking’ - If a handball player takes more than three steps without dribbling (bouncing the ball) or holds the ball for more than 3 seconds without bouncing it, shooting or passing, then that is deemed ‘walking' and possession is lost.

'Double dribble’ - Handball players cannot receive the ball and bounce it, then hold the ball, and bounce it again. This is termed ‘double dribble’ and is against the rules.

Railroad car A rolls at a certain speed and makes a perfectly elastic collision with car B of the same mass. After the collision
lozanna [386]

Answer:

The speed of the car B after the collision is same as the speed of the car A before collision.

Explanation:

lets take the mass of the car A = m kg

Initial speed of the car A = u m/s

The mass of the car B = m  kg

Initial speed of the car A = 0 m/s

The final speed of the car A = 0 m/s

The final speed of the car B = v

There is no any external force on the masses that is why the linear momentum will be conserve.  

Initial linear momentum = Final linear momentum

P = mass  x velocity

m u + m x 0 = m x 0 +  m v

m u  + 0 = 0 + m v

m u = m v

v= u

Therefore we can say that ,the speed of the car B after the collision is same as the speed of the car A before collision.
