a player uses a hockey stick to increase the speed of a 0.200 kg hockey puck by 6 m/s in 2 seconds is the acceleration 3 m/s2?

Yes. The mass doesn't matter in computing the acceleration, but it does affect the force required.

To determine the acceleration, we can use the equation:

acceleration = change in velocity / time taken

Given that the player increases the speed of the hockey puck by 6 m/s in 2 seconds, we can calculate the acceleration using the given values.

acceleration = 6 m/s / 2 s

Simplifying this equation:

acceleration = 3 m/s^2

So, the acceleration of the hockey puck is indeed 3 m/s^2.

To determine whether the acceleration is 3 m/s², we need to calculate the acceleration of the hockey puck.

Acceleration is defined as the change in velocity divided by the change in time. We are given that the hockey puck's speed increases by 6 m/s in 2 seconds.

First, let's calculate the initial velocity (u) of the hockey puck. Since there is no information given, we can assume that the initial velocity is 0 m/s (at rest).

Thus, the change in velocity (Δv) is 6 m/s, and the change in time (Δt) is 2 seconds.

Using the formula for acceleration:

acceleration (a) = (Δv) / (Δt)

a = 6 m/s / 2 s

Calculating the above:

a = 3 m/s²

Therefore, the acceleration of the hockey puck is indeed 3 m/s².
