Answer:

If the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 5 m/s to 2 m/s over one second, its constant acceleration is −3 m/s2.

If a particle has an initial velocity of 6 m/s and a constant acceleration of −2 m/s2, then:

when t=1, the velocity of the particle is 4 m/s

when t=2, the velocity of the particle is 2 m/s

when t=3, the velocity of the particle is 0 m/s

when t=4, the velocity of the particle is −2 m/s

when t=10, the velocity of the particle is −14 m/s.
