To travel at a constant speed of 16.6 meters per second on a level road for 2.81 hours, a car must exert a constant force of 343 newtons to overcome air resistance. how much charge in coulombs must the 10.9 battery move in order to maintain this force? remember that power = energy / time and power = force x velocity. one hour = 3600 seconds.

Q = 5.28 x 10⁶.

Explanation:

Power consumption of car = Force ( F ) x velocity ( v )

= 343 x 16.6 watt.

time = 2.81 hours

= 2.81 x 3600 s

Energy consumption = power x time

= 343 x 16.6 x 2.81 x 3600

=57.6 x 10⁶ J

energy output of battery = voltage x charge

= 10.9 x Q

Energy consumption by car = energy output of battery

10.9 x Q = 57.6 x 10⁶

Q = 5.28 x 10⁶.

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.
