Question

1) a body retards uniformly at a rate of 3 m/s^2 and stops in 10s. with what velocity was the bus travelling?

2) when two bodies move uniformly towards each other, then the distance between them decreases by 8m/s. if both the bodies move in the same firection with the same speeds, then the distance between them increases by 4 m/s . what are the speeds of two bodies?

Answer 1

the answer can be get by Newton first principle
