Which of these situations are examples of nonuniform motion in a straight line? Multiple select questions.

a car braking to a stop

an orbiting satellite

a ball rolling down a ramp

an elevator beginning to ascend

i think it's 35 meters

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
