Suppose that you're driving down the highway and a moth crashes into the windshield of your car. Which undergoes the greater impulse? a. the moth b. your cra c. both the same. Explain your answer

A 2 kg particle is acted on by a force as shown in the image below. The particle has an initial velocity vector (before the force is applied) of ₁ = 4 + 3) m/s and a final velocity vector (after the force is applied) of ₂ = -21+ 6) m/s. The force is applied for 3 s. a. Determine the impulse that has acted on the particle b. Determine the average force applied and its angle c. The net work done by the force acting on the particle (No change in particle height) Note: The image shown below is a top-down view of the particle and force. F X

A standard hammer has a head made of steel which bounces off the nails it hits. A special “dead blow” hammer has a hollow head which is loosely filled with tiny spheres of lead or sand that can rattle around inside the head. If you have a standard and a “dead blow” hammer whose heads have the same mass and you swing them at the same velocity, which one will deliver higher impulse to the nail it strikes? A. The normal hammer B. The dead blow hammer C. They will both deliver the same force.
