Answer to Question #12280 in Mechanics | Relativity for aneequa
Vf = V0 + at ==> t = (Vf - V0)/a.
t = (270 - 0.02)/0.005 = 53996 s.
find the average velocity of the body for its motion during this period in two ways by using
(i) the initial and final velocity of the body
Va = (Vf - V0)/2 = (270 - 0.02)/2 = 134.99 m/s;
(ii)the initial velocity, the acceleration and time?
Va = (Vf - V0)/2 = Va = (V0 + at - V0)/2 = at/2 = 0.005*53996/2 = 134.99 m/s.
