Question

28. The velocity of a body depends on time t according
to the equation v = 10 + 2t^2. The acceleration of the
body is
(1) Independent of time t
(2) Directly proportional to time t
(3) Inversely proportional to time t
(4) Directly proportional to square of time t-​

Answer 1

Answer:(2) directly proportional to t

Explanation:a=dv/dt

v=10+2t^2

a=4t

a is directly proportional to t.
