Question

Two hockey pucks with mass 0.1 kg slide across the ice and collide. Before the collision, puck 1 is going 15 m/s to the east and puck 2 is going 12 m/s to the west. After the collision, puck 2 is going 15 m/s to the east. What is the velocity of puck 1?

Answer 1

I got this wrong because the person that answered this didnt even answer the question but puck 1 is going 12 m/s west

Answer 2

After the collision, the velocity of puck 2 can be calculated as below,

From the conservation of momentum, the formula during a collision is given by: m1v1 + m2v2 = m1v'1 + m2v'2.

0.1 *15 + 0.1* 12 = 0.1* x + 0.1* 15

1.5 + 1.2 = x + 1.5

2.7 = x +1.5

X = 1.2

What is collision ?

"Collision, also called impact, in physics, the sudden, forceful coming together in direct contact of two bodies, such as, for example, two billiard balls, a golf club and a ball, a hammer and a nail head, two railroad cars when being coupled together, or a falling object and a floor. "
