An 810 kg dragster was decelerated by a parachute at 2.5 m/s2, as shown in the diagram. What is the tension in the cord at this moment?

double the distance = divide strength by 4

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.
