A bullet traveling horizontally at a speed of 370 m/s hits a board perpendicular to its surface, passes
through and emerges on the other side at a speed of
190 m/s.
Part A
If the board is 3.80 cm thick, how long does the bullet take to pass through it?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
