A rowboat passenger uses an oar to push the boat off the dock by exerting a force of 60.0 N for 2.0 s. What impulse acts on the boat?
120
To find the impulse acting on the boat, we need to use the impulse-momentum theorem, which states that the impulse acting on an object is equal to the change in momentum it experiences. Momentum is defined as the product of an object's mass and velocity.
The formula for impulse is:
Impulse = Change in momentum
Since we don't have the mass or the final velocity of the boat, we need to find the impulse in terms of the force and time.
The formula for impulse is also given by:
Impulse = Force × Time
Using this formula, we can calculate the impulse acting on the boat.
Impulse = Force × Time
Impulse = 60.0 N × 2.0 s
Impulse = 120 N·s
Therefore, the impulse acting on the boat is 120 N·s.
