A car is stopped at a red light. When the light turns green, it accelerates up to a velocity of 25 m/s over a period of 10 seconds. What is the
acceleration of the car?*

a = 2.5 [m/s²]

Explanation:

To solve this problem we must use the following equation of kinematics.

where:

Vf = final velocity = 25 [m/s]

Vo = initial velocity = 0 (star from the rest)

a = acceleration [m/s²]

t = time = 10 [s]

25 = 0 + (a*10)

a = 25/10

a = 2.5 [m/s²]

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.
