A car exits the highway at 26.0 m/s and enters a 230 m radius curve. After breaking uniformly for 4.00 seconds, the car exits the curve at 17.3 m/s. What is the magnitude of acceleration of the car midway through the curve relative to the forward motion of the car)? Tangential Acceleration; m/s2 Centripetal Acceleration: m/s? Magnitude of Total Acceleration: m/s2

20 The earth orbits the sun once every  π x 107 s at a distance of  1.5 x 1011 m.  Assuming uniform circular motion, what is its centripetal acceleration?  Group of answer choices 2.0 x 10-6 m/s2 9.0 x 10-3 m/s2 1.9 x 10-3 m/s2 6.0 x 10-3 m/s2

Car A rounds a curve of 107-m radius at a constant speed of 53 km/h. At the instant represented, car B is moving at 90 km/h but is slowing down at the rate of 3.0 m/s². Determine the velocity and acceleration of car A as observed from car B. Your answer is partially correct. Answer: VA/B = aA/B = 107 m 14.72 0 B CIDI i + -25 i + i 3 j) m/s j) m/s²

A ball is launched up a semicircular chute in such a way that at the top of the chute, just before it goes into free fall, the ball has a centripetal acceleration of magnitude 2g. (Figure 1) Figure 2R < 1 of 1 How far from the bottom of the chute does the ball land? Your answer for the distance the ball travels from the end of the chute should contain R. ► View Available Hint(s) D= [-] ΑΣΦ Submit Provide Feedback 6

A red car has a speed of 17.6 m/s and is driving on a circular track with a radius of 111 m. A blue car has a speed of 10.3m/s and is driving on a circular track with a radius of 55 m. What is the ratio of the centripetal acceleration of the red car to that of the blue car? ared/ablue =

here it explodes, relative to its firing point? P40. A train slews down as it rounds a sharp horizontal turn, going from 90.0 km/hr to 50.0 km/hr in the 15.0 s it takes to "round the bend". The radius of the curve is 150 m. Compute the acceleration at the moment the train speed reaches 50.0 km/hr. Assume the train continues to slow down at this time at the same rate.
