A bicyclist increases their speed from 10.0 m/s to 16.0 m/s, at an average rate of 1.5 m/s?. It will take her s to go through this acceleration Incorrect Question 13 0/2 pts In the previous problem, the bicyclist covers a distance of m while accelerating 6
Need help with number 2. 1. A bicyclist increases their speed from 10.0 m/s to 16.0 m/s, at an average rate of 1.5 m/s2. It will take her _4_ s to go through this acceleration. (Which I got 4 seconds) 2. In the previous problem, the bicyclist covers a distance of ___________ m while accelerating. (not sure how to find the covered distance while accelerating.)

The angular speed of a ceiling fan increases uniformly 10.0 revs/s to 16.0 revs/s, and does so in 2.2 s (a) What is the angular displacement of the blades during the acceleration, expressed in revolutions? (b) What is the angular acceleration, expressed in standard units?
1) An 18-year-old runner can complete a 10.0 km course with an average speed of 4.52 m/s. A 50-year-old runner can cover the same distance with an average speed of 4.07 m/s. How much later (in seconds) should the younger runner start in order to finish the the course at the same time as the older runner? s 2) A sprinter explodes out of the starting block with an acceleration of +3.8 m/s2, which she sustains for 1.4 s. Then,...

A bicyclist maintains a constant speed of 4.00 m/s up a hill that is inclined at 10.0 degrees with the horizontal. Calculate the work done by the person and the work done by gravity if the bicycle moves a distance of 19.0 m up the hill. The combined mass of the rider and the bike is 88.0 kg. 1) Calculate the work done by gravity. 2) Calculate the work done by the person.
