Uniform accelerated motion (UAM) equations:
We'll solve for time using kinematics:
A 0.450-kg hammer is moving horizontally at 7.00 m/s when it strikes a nail and comes to rest after driving the nail 1.00 cm into a board. Assume constant acceleration of the hammer-nail pair.
a. Calculate the duration of the impact.
b. What was the average force exerted on the nail?
