Chapter 12, Problem 110P

An accelerometer C is mounted to the side of the roller-coaster car and records a total acceleration of 3.0g as the empty car passes the bottommost position of the track as shown. If the speed of the car at this position is 205 km/h and is decreasing at the rate of 18 km/h every second, determine the radius of curvature p of the track at the position shown. Answer: p= i m 0.76 m

The velocity of a particle moving in the x-y plane is given by (5.92i +4.07j) m/s at time t = 5.92 s. Its average acceleration during the next 0.019 s is (2.2i + 3.2j) m/s². Determine the velocity v of the particle at t = 5.939 s and the angle 8 between the average- acceleration vector and the velocity vector at t = 5.939 s. Answers: v = (i 0 = wpad i+ IN j) m/s

At the instant shown, object A's speed is VA = 5.9 m/s, and it is increasing at 0.5 m/s²; object B's speed vg = 1.0 m/s, and it is decreasing at 1.3 m/s². Determine the magnitude of the relative velocity of A with respect to B. Object Bis travelling along a circular path with radius of r = 12 m. The distance between A and B is d = 3.0 m, the angle is = 25°. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point and proper unit. 0 VA d Your Answer: Answer VB units

A. Determine the direction of the crate’s velocity at this instant. B. Determine the magnitude of the crate’s acceleration to this instant.

Collars A and B slide along the fixed right-angle rods and are connected by a cord of length L = 8.3 m. Determine the acceleration of collar B when y = 3.0 m if collar A is given a constant upward velocity vA = 2.48 m/s. The acceleration of B is positive if to the right, negative if to the left.

A race car enters the circular portion of a track that has a radius of 70 m. When the car enters the curve at point P, it is travelling with a speed of 120 km/h that is increasing at 5 m/s2. Three seconds later, determine the following

A boat is travelling along a circular path having a radius of 30 m. Determine the magnitude of boat's acceleration, a, when the speed is 5.7 m/s and the rate of increase in the speed is 7.5 m/s² Enter a1: m/s2 Enter a : m/s²

The automobile travels from a parking deck down along a cylindrical spiral ramp at a constant speed of v=1.5 m/s. If the ramp descends a distance of 12 m for every full revolution, determine the magnitude of the car's acceleration as it moves along the ramp, r = 10 m. Hint: Note that the tangent to the ramp

During a parasailing ride, the boat is traveling at a constant 38 km/hr with a 200-m long tow line. At the instant shown, the angle between the line and the water is 30º and is increasing at a constant rate of 2º/s. Determine the velocity and acceleration of the parasailer at this instant.   The velocity of the parasailer is m/s ⦨ °. ? (This is incorrect)   The acceleration of the parasailer is 0.244m/s2 ⦪ 30 °. (This is correct)   Sub Note: (I posted this question before, but unfortunately the expert that answered it got that part wrong pls rectify this for me, by checking out the image!)
