A racetrack is constructed such that two arcs of radius 80 m at Ⓐ and 40 m at Ⓑ are joined by two stretches of straight track as in Figure 7.8. In a particular trial run, a driver travels at a constant speed of 50 m/s for one complete lap.1. The ratio of the tangential acceleration at Ⓐ to that at Ⓑ is(a) | (b) J (c) 2 (d) 4 (e) The tangential acceleration is zero at both points.2. The ratio of the centripetal acceleration at Ⓐ to that at Ⓑ is(a) J (b) \ (c) 2 (d) 4 (e) The centripetal acceleration is zero at both points.|3. The angular speed is greatest at(a) Ⓐ (b) Ⓑ (c) It is equal at both Ⓐ and Ⓑ. Figure 7.8(Quick Quiz 7.6)

(a)

To determine

The ratio of tangential acceleration at (A) to that at (B).

Explanation

Given Info: Radius of arc (A) is 80.0m, radius of arc (B) is 40.0m, the constant speed of the driver is 50.0m/s

(b)

To determine

The ratio of centripetal acceleration at (A) to that at (B).

(c)

To determine

The point of greatest angular speed.
