Current Attempt in Progress Car A rounds a curve of 125-m radius at a constant speed of 39 km/h. At the instant represented, car B is moving at 99 km/h but is slowing down at the rate of 4.7 m/s². Determine the velocity and acceleration of car A as observed from car B. Answer: VA/B = 125 m (i aA/B = (i 114 B i + i i+ j) m/s j) m/s²

2/193 For the instant represented, car A has a speed of 100 km/h, which is increasing at the rate of 8 km/h each second. Simultaneously, car B also has a speed of 100 km/h as it rounds the turn and is slowing down at the rate of 8 km/h each second. Determine the acceleration that car B appears to have to an observer in car A. Ans. agA = -4.44i + 2.57j m/s2 -300 m B A y--

A car moved on a horizontal path from rest at constant acceleration from point A until it reached its maximum speed when passing by At point b it took 4 seconds, and after point B it continued its movement but at a slowdown of -3 m / s2 until it stopped at c Categorical The idling distance of 13.5 m. Find: 1. The distance the car traveled while accelerating from a to b 2. The car's rate of acceleration (acceleration) 3. The car's maximum speed from point b 4. The time the car took when slowing down from b to c

At the instant shown, cars A and B are travelling at the speeds shown. If B is accelerating at 1200 mi/h2 while A maintains a constant speed, determine the magnitude of the velocity and acceleration of B with respect to A. Car B moves along the curve having a radius of curvature of 0.7mi.  show all the steps in the solution please

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 ⦨ °. ?   The acceleration of the parasailer is m/s2 ⦪ °. ?   Note: please show step by step solution. Hence, double check the solution. For correction purposes!. I require  handwritten working out please!.

At the instant shown, cars A and B travel at speeds of 70 mi/h and 50 mi/h, respectively. If B is increasing its speed by 1100 mi/h², while A maintains a constant speed, determine the velocity and acceleration of B with respect to A. Car B moves along a curve having a radius of curvature of 0.7 mi.

The x-coordinate of a particle in curvilinear motion is given by x = 2t² - 3t where x is in meters and t is in seconds. Also, the particle has an acceleration in the y-direction given by a, 8- sec. If the velocity of the particle in the y-direction is 3 m/sec when t=0, calculate the magnitudes of the velocity v and acceleration a of the particle when t=2 sec. and the angles these vectors make with the x-axis at the same instant.

This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Block B moves downward with a constant velocity of 26 mm/s. At t = 0, block A is moving upward with a constant acceleration, and its velocity is 36 mm/s. Consider that at t =3 s, slider block C has moved 57 mm to the right.   Determine the velocity of slider block C at t = 0. (You must provide an answer before moving on to the next part.)   When t = 0, the velocity of slider block C is mm/s. →?   Note: please show step by step solution.
