A hockey player shoots a puck, exerting a constant force of 30.0 N on the hockey puck for 0.16 seconds. What is the magnitude of the impulse given to the puck?
190 kg ∙ m/s
98 kg ∙ m/s
9.6 kg ∙ m/s
4.8 kg ∙ m/s
Impulse is force x time.
One of your choices will meet that criterion.
In case you are confused about units,
1 kg m/s = 1 Newton-second

To calculate the magnitude of the impulse given to the puck, we can use the formula for impulse:
Impulse = Force × Time
Given:
Force = 30.0 N
Time = 0.16 seconds
Substituting these values into the formula, we get:
Impulse = 30.0 N × 0.16 seconds
Now, let's solve this equation:
Impulse = 4.8 N·s or kg·m/s
Hence, the correct answer is 4.8 kg·m/s.
