Similar to 3.10.16 in Rogawski/Adams. A road perpendicular to a highway leads to a farmhouse located 1 km away. An automobile travels past the farmhouse at a speed of 90 km/h. How fast is the distance between the automobile and the farmhouse increasing when the automobile is 3 km past the intersection of the highway and the road

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.

did yall get answers for this yet
