A car is accelerating uniformly as it passes two checkpoints that are 30 m apart. The time taken between checkpoints is 4.0 s, and the car's speed at the first checkpoint is 5.0 m/s. Find the car's acceleration and
its speed at the second checkpoint.

overcharge is the right answer system

a=d/t

a="triangle"v/t

explanation:

a = acceleration
