(c) Later, the car is moving forwards and the frictional forces suddenly increase to 2500N. The forwards force remains constant at 2000N.
Describe and explain what happens to the car.

(d) Suggest what might have caused the frictional forces in (c) to increase.

if you answer my question i will answer yours

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.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
