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. Find vA/B and vA/B.Answers: vA/B = (___ i +___ j) m/s vA/B = ____ m/s
The quarterback Q throws the football when the receiver R is in the position shown. The receiver's velocity is constant at 10.3 yd/sec, and he catches passes when the ball is 5.5 ft above the ground.

20-50. At the instant shown, the arm OA of the conveyor belt is rotating about the z axis with a constant angular velocity w, = 6 rad/s, while at the same instant the arm is rotating upward at a constant rate w = 4 rad/s. If the conveyor is running at a constant rate i = 5 ft/s, determine the velocity and acceleration of the package Pat the instant shown. Neglect the size of the package. tr= 6 ft w= = 6 rad/s, \e = 45° w = 4 rad/s
The car A has a forward speed of 17 km/h and is accelerating at 3.9 m/s?. Determine the velocity and acceleration of the car relative to observer B, who rides in a nonrotating chair on the Ferris wheel. The angular rate Q = 2.7 rev/min of the Ferris wheel is constant. 2= 2.7 rev/min B 36 R = 9.5 m A. Answers: VA/B = ( i i+ i j) m/s aA/B = ( i i+ i j) m/s2 一 N
The drag racer P starts from rest at the start line S and then accelerates along the track. When it has traveled 120 m, its speed is 40 m/s and it is accelerating forward at 11.4 m/s². For that instant, determine the values of 7 and relative to axes fixed to an observer O in the grandstand G as shown. 26 m Answers: 7 = Ö = i i Hom P m/s² rad/s²
The drag racer P starts from rest at the start line S and then accelerates along the track. When it has traveled 83 m, its speed is 50 m/s. For that instant, determine the values of r and 0 relative to axes fixed to an observer O in the grandstand G as shown. 40 m Answers: r = 0 = i i P m/s rad/s
The belt is travelling to the right at some speed v, while the pipe is rolling without slipping at o = 4 - 1.5 m rad/s as shown. If the center of the pipe G appears to an observer on the ground to move at 2 m/s to the left, determine the velocity of the Belt В belt v.
The sphere P travels in a straight line with speed v= 10.3 m/s. For the instant depicted, determine the corresponding values of r and as measured relative to the fixed Oxy coordinate system. Assume x = 6.5 m, y = 4.6 m, p = 23° Answers: r = 0 = i i P m/s rad/s
Please help now I really need it, thank you
The speedboat B is cruising to the north at 78 mi/hr when it encounters an eastward current of speed vC = 11 mi/hr but does not change its heading (relative to the water). Determine the subsequent velocity of the boat relative to the wind and express your result as a magnitude vrel and compass direction θ measured clockwise from north. The current affects the motion of the boat; the southwesterly wind of speed vW = 25 mi/hr does not.
