To find the initial speed of the puck, we can use the Pythagorean theorem.
The initial speed of the puck can be found using the formula:
initial speed = √(𝑣𝑥^2 + 𝑣𝑦^2)
Substitute the given values:
initial speed = √(12^2 + 18^2)
initial speed = √(144 + 324)
initial speed = √468
initial speed ≈ 21.63 m/s
Therefore, the initial speed of the puck is approximately 21.63 m/s.
A hockey puck is given an initial velocity such that 𝑣𝑥 = 12 m/s and 𝑣𝑦 = 18 m/s, where the 𝑥 – 𝑦 plane is horizontal.
