A car started from rest and accelerates with 2.4 m/s2 for 8.8 seconds. It then travels with the constant velocity it has achieved for another 9.9 seconds. Then it finally slows to a stop with a constant acceleration of 3.4 m/s2. How far does the car travel after starting from rest?

367.616 m

Explanation:

The distance it travels for the 1st segment is

The constant velocity that it achieves in the 2nd segment is

The distance it travels in the 2nd segment is

The distance it travels in the last segment when coming from 21.12 m/s to rest (0 m/s) at the rate of -3.4 m/s2 is

The total distance is has traveled from rest is

92.928 + 209.088 + 65.6 = 367.616 m

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the sun.jul 26, 2018

explanation:

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
