The speed of the hockey puck towards the goal is 41.04 m/s.

Newton's second law of motion

Newton's second law of motion states that the force applied to an object is directly proportional to the product of mass and acceleration of the object.

F = ma

where;

  • m is the mass
  • a is the acceleration

[tex]F = \frac{mv}{t} \\\\mv = Ft\\\\v = \frac{Ft}{m} \\\\v = \frac{29.5 \times 0.16}{0.115} \\\\v = 41.04 \ m/s[/tex]

Thus, the speed of the hockey puck towards the goal is 41.04 m/s.
