Question

If the initial speed of a particle is u and its
acceleration is given as a = At, where A is
constant and t is time, then its final speed v will
be given as
(1) U + At
ST ut At
(3) U+ AB
(4) ut At
​

Answer 1

Answer:

velocity at any time instant 't' -

v = u + (1/2) At^2

Explanation:

a = At

=> dv/dt = At

=> dv = Atdt

after integrating both side,

v - u = (1/2) A t^2

=> v = u + (1/2) At^2
