A toy car starts from rest, and after moving for 10 seconds acquires a velocity of 0.5m/s. Find the velocity at the 10th second and the distance covered as well.
Velocity at the 10th second
Distance at the 10th second

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.
