While the swing bridge is closing with a constant rotation of 0.5 rad/s, a man runs along the roadway such that when d = 10 ft he is running outward from the center at 5 ft/s with an acceleration of 2 ft/s2, both measured relative to the roadway. determine his velocity and acceleration at this instant.

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
