Assignment Help Mechanical Engineering

The acceleration of a particle is defind by the relation a = - 0.8 v , where a is expressed in m/s^2 and v m/s. knowing that at t=0

the velocity is 1m/s. determine:

a) the distance the particle will travel before coming to rest.

b) the time required for the particle's velocity to be reduced by 50 percent of its initial value.
