A car is skidding out of control on a horizontal icy (frictionless) road. It has a mass of 2000 kg and it is headed directly at Lois Lane at a speed of 45.0 m/s. When the car is 200 m from her, Superman begins to exert a steady force on the car, F, relative to the horizontal with a mag-
nitude of 1.30 X 10^4N (he's a strong dude) at a down-
ward angle of 30°. Was Superman correct? Was this force enough to stop the car before hitting Lois?

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.
