An automobile travels to the right at a constant speed of 48 ft/s. If the diameter of a wheel is 22 in., determine the velocity of point E. 30 90 E 22 in.

P16-2. Establish the location of the instantaneous center of zero velocity for finding the velocity of point B. -2 m 05 m 4 rad/s

please double check your answer

Car A is traveling at the constant speed of 58 km/h as it rounds the circular curve of 350-m radius and at the instant represented is at the position θ = 42°. Car B is traveling at the constant speed of 69 km/h and passes the center of the circle at this same instant. Car A is located with respect to car B by polar coordinates r and θ with the pole moving with B. For this instant determine vA/B and the values of r˙ and θ˙ as measured by an observer in car B. For this instant determine the values of r˙ and θ˙ as measured by an observer in car B.Answers: r˙ =  m/s θ˙ =  rad/s

4. Rod AB is attached to collars at its ends by ball- and-socket joints. If the collar A has a velocity of VA = 3 ft/s. determine the angular velocity of the rod and the velocity of collar B at the instant shown. Assume the angular velocity of the rod is directed perpendicular to the rod. 4 ft 2 ft B 3 ft/s A 4 ft y
