Question
the next column or page-find all choices before answering. A bug completes one lap along the edge of a circular planter of radius 17.5 cm in 17.23 s How fast was it traveling? Answer in units of cm/s. How fast in m/s? Answer in units of m/s. A person travels by car from one city to another. She drives for 36 min at 83.7 km/h, 14.6 min at 118 km/h, 53.3 min at 32.5 km/h, and spends 15.7 min along the way eating lunch and buying gas. Determine the distance between the cities along this route. Answer in units of km. Determine the average speed for the trip. Answer in units of km/h. A car accelerates uniformly from rest to a speed of 93.8 ml/h in 9.14 s. Find the constant acceleration of the car. Answer in units of m/s^2. Find the distance that the car travels during this time. Answer in units of m. A truck covers 36.7 m in 8.2 s while smoothly slowing down to a final speed of 2.9 m/s. Find its original speed. Answer in units m/s. Find its acceleration. Answer in units of m/s^2.Explanation / Answer
Problem 1)
a) v = 2 x pi x r/ t = 2 x 3.14 x 17.5/17.23 = 6.38 cm/s
b) v = 6.38/100 = 0.0638 m/s
