Chapter 16, Problem 73P

The distance y = 2.8 m. Find the upward velocity of A if the downward velocity of B is 3.8 m/s. Neglect the diameters of the pulleys. A 13 m B

Rotation of bar OA is controlled by the lead screw which imparts a horizontal velocity v to collar C and causes pin P to travel along the smooth slot. Determine the values of r and 6, where r = OP, if h = 160 mm, x = 120 mm, and v = 25 mm/s at the instant represented. h C

Give me right solution with clear calculations. Please remember I want 100% right solution. Thank you

Car A is traveling at the constant speed of 48 km/h as it rounds the circular curve of radius r - 310 m and at the instant represented is at the position 8 - 43°. Car B is traveling at the constant speed of 58 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 with the pole moving with B. For this instant determine VA/B and the values of it and as measured by an observer in car B. Answers: VA/B- ŕ- 0- i 27.4 i -14.4 0.075 0 m/s m/s rad/s

The end B of rod AB moves up the right half of the parabolic slope at the constant speed of 0.3 m/s as shown in the figure. Determine the velocity and acceleration of point A, which is at the origin at the given instant.

If at the instant shown the speed of the collar C is 2.0 m/s upwards, determine the speed of point A. r1= 0.289 m r2= 0.383 m r3= 0.220 m θ= 30 °
