Chapter 16, Problem 45P

Determine an expression for the velocity vA of the cart A down the incline in terms of the upward velocity vB of cylinder B. If h = 1.48 m, x = 4.15 m, and vB = 1.90 m/s, what is vA?

A Ferris wheel provides car A (120 kg) a constant increase of speed of a = 10 m/s . In order to determine the sizes of bolts to be used for the pin connection at A, calculate the horizontal and vertical components of the reaction when the speed reaches v = 15m/s p-4m

The 150-lb car of an amusement partk ride is connected to a rotating telescopic boom. When r = 15 ft, the car is moving on a horizontal circular path with a speed of 30 ft/s. If the boom is shortened at a rate of 3 ft/s, determine the speed of the car when r = 10 ft. Also, find the work done by the axial for F along the boom. Neglect the size of the car and the mass of the boom.

A motorcycle starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/sec2 until it reaches a speed of 50 ft/s and maintains this speed throughout the duration of the motion. Also, when t = 0, a car located 6000 ft away, travels towards the motorcycle at a constant velocity of 30 ft/s. Determine the time at which the two vehicles pass each other,Calculate the distance traveled by the motorcycle the moment that the two vehicles pass each other, Calculate the distance traveled by the car the moment that the two vehicles pass each other.

3/98 The small cart has a speed va = 4 m/s as it passes point A. It moves without appreciable friction and passes over the top hump of the track. Determine the cart speed as it passes point B. Is knowledge of the shape of the track necessary? VA= 4 m/s 1.8m. A B

The 2-kg block B and 15-kg cylinder A are connected to a light cord that passes through a hole in the center of the smooth table. If the block is given a speed of v = 10 m/s, determine the radius r of the circular path along which it travels.

The 3950-lb van is driven from position A to position B on the barge, which is towed at a constant speed vo= 6 mi/hr. The van starts from rest relative to the barge at A, accelerates to v= 17 mi/hr relative to the barge over a distance of d = 73 ft, and then stops with a deceleration of the same magnitude. Determine the magnitude of the horizontal force F between the tires of the van and the barge during this maneuver. Answer: F= i + B lb
